Abstract—Crossover is the most important step in genetic algorithm, which passes on good genes
of the parents to the next generation. However, the crossover operator can’t ensure the offspring
finding the globally optimum because of its blind search. A weighted crossover operator is
proposed to overcome the disadvantages. Weighted values are calculated according to the adaptive
values of the parents. One offspring is generated through the weighted crossover operator. On this
basis, an oriented weighted crossover operator is proposed to increase the probability of finding
excellent solution genes. The convergence of the genetic algorithm based on this crossover
operator is proved. Experiments show that the genetic algorithm based on this operator has a good
performance in searching optimum.

Abstract—The problem of considering the setup times in scheduling with non-sequence constraint
between operations has been researched, but there are no researches on the problem of considering
the setup times in processing and assembly integrated scheduling of complex multi-product
dynamic scheduling with sequence constraint between operations. So, a complex multi-product
dynamic scheduling algorithm is proposed, considering sequence-dependent setup times. The
algorithm constructs the virtual manufacturing tree in the way of root alignment and converts the
complex multi-product dynamic scheduling problem to the complex single product scheduling
problem. After the scheduling sequence of operations is determined, the starting time of each
operation is determined by dynamically inserting setup time once. As the proposed algorithm
avoids several movements of the scheduled operation when the setup time is inserted, the time
complexity is sharply reduced. Theoretical analysis and examples show that the proposed
algorithm not only can solve the complex multi-product dynamic scheduling problem with
sequence-dependent setup times, but also is simple and practical.

Abstract—The control algorithm on coordination behavior of a flocking system consists of three
components; they are collision avoidance, cohesion and alignment. The three components are
realized by application of interactions between the agents in the system as well as guidance of the
environment. To achieve better coordination through interactions between agents, the concept of
fuzzy neighborhood is introduced in this paper. And the fuzzy grading is utilized to describe it. For
agent , the intensities of neighborhood, characterized by numbers in the range of 0-1, vary with the
distances between the other agents and agent . The smaller the distance, the larger the intensity
and its value tends closer to 1; the larger the distance, the weaker the intensity and its value tends
closer to 0. By this method, interactions and coordination between agents have been built to obtain
the ultimate coordination of the flocking system.

Abstract—The issue of PID controllers designing for a typical class of networked cascade control
systems with constant network-induced delays is addressed. Cascade control system, wherein the
control loops are closed via a real-time network, is called a networked cascade control
system(NCCS for short). The system configuration for a typical class of NCCSs is analyzed, and

responses, the PID tuning parameters of the primary and secondary controllers are proposed in

control performance indices for the NCCS explicitly indicate the superiority of the proposed
approach to improve the system performance.

Abstract—During to the non derivability for triangle wave reference trajectory, whose
high-frequency harmonics will stimulate the resonant modes in the high-frequency voice coil
motor (VCM), the traditional speed and acceleration feed forwards can not be achieved. In this
paper, the triangle wave was Fourier transformed to get its Fourier series composed of several sine
functions, which are high order differential. After derivation calculus to the sum function of the
series, the first and second order derivatives of the sum function were obtained. By making the
inverse Fourier transform to the derivatives of sum function, the first and second order differential
of the triangle wave were obtained and the speed and acceleration feed forwards under triangle
wave reference were achieved. In the feedback controller, an incomplete differential PID-like
neural network controller was introduced and improved. The dynamic recurrent neural network
(DRNN) was used to real-timely identify the system’s Jacobian information. The feedback
controller was used to compensate the approximation error in the feedforward and suppress the
high frequency harmonic components in order to stabilize the systems and eliminate the residual
error. The simulation results show that the system is of small steady-state error and high
positioning accuracy, and the system requirements are also met under high-frequency inputs.

Abstract—This paper explores the satellite shield attitude planning for low observable satellites
equipped with signature suppression shields. The on-orbit satellite’s operational effectiveness and
survivability are coupled with its radar cross section (RCS) and laser cross section (LCS) in threat
directions, which are determined by the shield’s attitude. This paper presents a real-time satellite
shield attitude planning algorithm (RSSAPA), which aims to reduce the satellite’s RCS and LCS
in threat directions by limited satellite shield attitude control in real-time. The algorithm
establishes a new mathematical model based on satellite orbit, threat distribution and earth
curvature directly, and develops an improved adaptive genetic algorithm (IAGA) with novel
crossover and mutation strategies, to reduce the computational complexity and ensure the
real-time performance. Also, curved surface pixel method (CSPM) is introduced in RSSAPA to
calculate satellite’s RCS, and a refined CSPM is developed to complete the satellite’s LCS
calculation at the same time. According to the simulation results, the algorithm is proved to be
efficient.

Abstract—In this paper, we describe a method for removing noise from digital images, based on
bilateral filter and Gaussian scale mixtures (GSM) in shiftable complex directional pyramid
(PDTDFB) domain. Firstly, the noisy image is decomposed into different subbands of frequency
and orientation responses using a PDTDFB transform. Secondly, the bilateral filter, which is a
nonlinear filter that does spatial averaging without smoothing edges, is applied on the
approximation subband. Finally, the distribution of detail subbands of PDTDFB coefficients is
modeled with GSM, and the statistical model is then used to obtain the denoised detail coefficients
from the noisy image decomposition by Bayes least squares estimator. Extensive experimental
results demonstrate that our method can obtain better performances in terms of both subjective and
objective evaluations than those state-of-the-art denoising techniques. Especially, the proposed
method can preserve edges very well while removing noise.

scheduling scheme for multi-service networks, called PRI/DWRR+, is designed based on the
DWRR+ algorithm. Eventually, in the simulation test of the new scheduling scheme, the PHB

Abstract— the train scheduling is a crucial part of modern railway operation system. The train
schedule optimization problem is exceptionally large-scale and hardly solved via the conventional
mathematical method. In this paper, the double-track railway train schedule optimization is
concerned. Based on the characteristics of the double-track railway operation system, a novel
train schedule optimization model based on clonal selection differential evolution (CSDE)
algorithm is proposed. In comparison to the traditional differential evolution method, the
modifications include: (1) clonal selec-tion mechanism with an auxiliary pool is introduced to
provide the best individuals with more evolution opportunities; (2) an apoptosis process is
employed in which worst individuals will be either extinct or regenerated in probability; (3) the
population is in a dynamic balance. The novel method contains more control variables and can be
converted into ordinary differential evolution problem with specific parameters setting. In a
computational instance, the implementing result indicates that the proposed model and algorithm
are practical and feasible for double-track train schedule optimization problem.

Abstract— For Unmanned Air Vehicles (UAV) to flight autonomously, the decision making
system must be developed to replace the remote control by the pilot. To shorten the learning time
and increase the real-time response, the inverse-design (ID) method is presented to calculate the
control input decision inversely by using the desired output and the predictor-corrector algorithm
which uses the proportional-integral predicted initial value to compute the control inputs. In the
mission description process, the quasi-uniform B-spline is used to generate the desired output by a
succession of control points. The genetic algorithm (GA) is also implemented to compare the
computing time and the development complexity with the ID method. Simulation shows the ID
method based on the predictor-corrector algorithm can be validly and efficiency used in the
autonomous flight control system decision making of the UAV, and the ID method is preponderant
in online computing, development and computing time reducing than the GA. The analysis and ID
method presented in this paper will produce a direct benefit in relation to the decision making
method and the design of the UAV autonomous flight control system.

distributed artificial intelligence domain in recent years. Many efficient and flexible distributed
reputation models have been developed. Nevertheless the heterogeneity of agents(including

forward to support interoperation among heterogeneous reputation models in this paper. The
elements of the framework, such as rating, recommendation are formally defined. The issues of
recommendation report forms, reputation integration, and witness reputation are discussed. Before
depicting the agent architecture, we provide a case about how a present reputation model is
implemented in the framework. The work will be beneficial to combine heterogeneous reputation
models and to integrate applications with different reputation models.

Abstract—This paper considers a new transportation problem: Lane Reservation Problem in Time
Constrained Transportation. This kind of problem comes from large sportive events in a city or
region where the travel time between sportive villages and stadium should fall in a strict time
window. To guarantee the athlete transportation in time, the problem consists in temporarily
creating special lanes on roads in the transportation network while minimizing the traffic impact to
the daily traffic. The corresponding objective is to minimize the total weighted cost of reserved
lanes. In this paper, we construct a new integer linear programming model for the problem, which
describes the problem more accurately. Because the complexity of the problem, we propose an
efficient tabu search heuristic to obtain near optimal solutions and compare it with the solutions
obtained by the heuristic proposed in [1]. Computational results show that average gap between
solutions obtained with the proposed tabu search heuristic and by a software package (Cplex) is
less than 5.71% for large size instances, and the average computational time of solutions proposed
by the heuristic is less than 39.414 second.

Abstract—A facial expression recognition method based on the fuzzy information fusion of the
local features is proposed. Each original image is divided into many sub-images and all training
sub-images from the same position construct a new training subset. The traditional PCA (principal
component analysis) operates directly on a set of new training subsets respectively and a set of
projection sub-spaces can be obtained. The local sub-feature of an unknown face can be extracted
by projecting each sub-image onto the corresponding sub-space. According to these local
sub-features, the membership grades of the test sub-images to the training sub-images can be
determined. The identity of an unknown facial expression image is determined by the fuzzy fusion
which aggregates the local sub-features. The experiments on JAFFE database show the
effectiveness of the proposed method.

Abstract—Microturbine generator system is one of the most promising distributed generation
systems because it is small, efficient and mobile. When it is running, the high-frequency
alternating current of permanent magnet synchronous generator generating must be rectified and
inverted into 50Hz AC to meet the user requirements. Normally, the diode rectifier is used. When
we need to regulate voltage, the DC/DC converter is applied and the generator current is distorted
and the power factor is low. Therefore, PWM rectifier is utilized to regulate voltage and power
factor based on power control scheme. In microturbine system, the maximum frequency is
1200Hz and active power is severely impacted by the term of reactive power, so as to make DC
link voltage unstable. We use feedforward scheme to automatically compensate for active power
changing , so a stable DC link voltage and high power factor can be achieved. The results of
simulation and experiment show that the proposed scheme is effective and practicable.

avoidance. We attempt to show the reasons why individuals in the natural world can get
synchronization, and implement obstacle collision avoidance of the swarm system using artificial

Abstract— Clustering documents enable the user to have a good overall view of the information
contained in the documents. Most classical clustering algorithms assign each data to exactly one
cluster, thus forming a crisp partition of the given data, but fuzzy clustering allows for degrees of
membership, to which a data belongs to different clusters. In this system, documents are clustered
by using fuzzy c-means (FCM) clustering algorithm. FCM clustering is one of well-know
unsupervised clustering techniques. However FCM algorithm requires the user to pre-define the
number of clusters and different values of clusters corresponds to different fuzzy partitions. So the
validation of clustering result is needed. PBM index and F-measure are used for cluster validity.

Abstract—This paper proposes a new robust adaptive filtering algorithm for stereophonic acoustic
echo cancellation in impulsive noise environment. The well-known conventional two channel
normalized least mean square (TCNLMS) algorithm performs very poorly when either the input or
the desired signal is corrupted by impulsive noise. By employing robust M-estimate technique, a
new two channel normalized least mean M-estimate (TCNLMM) algorithm is proposed, which
only imposes mild additional computational overhead but achieves improved robustness to
impulsive noises over its NLMS counterpart. Experiments are also conducted to verify the
efficiency of the new algorithm.

physical systems, and this description is of great advantage than normal systems. Consequently
and undoubtedly, descriptor systems have led us into a virgin land which is full of challenges and
opportunities. Because of the specialization of derivative matrix of descriptor systems, some
performances could not be realized by proportional feedback, but it could be realized by derivative
feedback under some conditions, which implies the superiority of derivative feedback. Finally, an
example is given to illustrate the validity of our method.

Abstract—In embedded system design, hardware/software (HW/SW) partitioning is the
NP–complete problem which searches reasonable composition of hardware and software
components which not only satisfies the constraint of hardware but also optimizes the execution
time. Blocks derive from the functional specification internally represented as control/data flow
graph. In this paper, the model of the embedded system is extended so that resource contentions
are taken into account. A GA-based algorithm is proposed on the basic of the model, in which
“serial blocks” are calculated by NAP. The algorithm can lead to a more precise design space
exploration. Experimental results show that, comparison with exhaustive search method, the
algorithm we proposed can be conveniently implemented HW/SW partitioning with resource
contentions.

Abstract---This paper develops a new method for minimizing intersection delay based on linear
and nonlinear program. On the basis of geometric construction, a new set of formulas are
proposed to estimate the steady-and-oversaturation delay. As a dynamic model, it can
automatically allocate the green time to obtain the minimal delay. Since the objective function of
delay is linear or nonlinear, only the combination of linear and nonlinear program can be applied
to random situation. The two objective functions, subject to corresponding constraints, can

Abstract—A neural network (NN)-based backstepping adaptive control is proposed for the
stabilized platform system of shipborne weapons (SPOSW) with uncertain nonlinear friction
torque and load disturbance. First, with the using of NN approximator, an equivalent model is
developed. Where the NN is used to estimate the uncertain nonlinear friction torque. Then, based
on the equivalent model, address the problem of reconstruction error and disturbance load, an
adaptive backstepping control scheme is proposed for the stabilized platform system. Moreover,
the analysis of stability can be completed by Lyapunov stability theory, and the convergence rate
of the tracking error can be governed by the choice of the control parameter values. Finally, to
demonstrate the effectiveness of the proposed control scheme, simulation results are illustrated.

Abstract—STandard for the Exchange of Product data-compliant Numerical Control (STEP-NC)
is a new model of data transfer between CAD/CAM systems and CNC machines. It remedies the
shortcomings of ISO 6983 by specifying machining processes rather than machine tool motion,
using the object-oriented concept of Workingsteps. STEP-NC is being developed concurrently
under two different subcommittees of ISO Technical Committee 184, Industrial automation
systems and integration so that two different standards, ISO 14649 Data model for computerized
numerical controllers and ISO 10303-238 Application interpreted model for computer numeric
controllers are generated, both of which can be represented in 10303-21. In this paper, ISO 14649
NC program in Part21 relative to Example 1 in the ISO 14649-11 is explained in detail so that
people can easily understand the object-oriented data model and the advantages of ISO 14649
from the actual example other than abstract and unintelligible theory. Probably, more beginners
can get some revelation so that STEP or STEP-NC can get more attention and their development
will be faster.

difficulties emerge in planning annual coal purchase and allocation schedule, e.g., with multiple
sources, multiple destinations, different shipping vessels. So it is important to research on the
transportation and storage problems for regional power coal allocation planning of China. In this
study, these concerns are formulated as transportation and storage problems to realize the

optimization model is proposed to solve transportation and storage problems for regional power
coal allocation planning integrating storage capacities of the different kinds of enterprises in the
supply chain, which considers interactive effect on multiple participants, such as regional power
plants, coal transportation companies, logistics centers, coal storage centers. A case study

Abstract—Most of the traditional dynamic multi-criteria decision-making methods utilize only
differences of the systems’ evaluation values (which can be called absolute difference), then the
conclusion of the evaluation is unfair to some evaluated objects. In consideration of disadvantages
of the traditional method, a new method based on integration of absolute and relative differences
is suggested. In this method, differences of systems’ developing status (relative difference) are
taken into consideration. So more information can be put in and then produced out so as to
approach reality closer. And also both the subjective and objective information are integrated.
Finally, a numerical example was given to illustrate the effectiveness of the proposed method.

Abstract—This paper analyzes the 20 percent Sn4+-doped titania films who were prepared on the
quartz glass humidity sensor by complex impedance analysis, improves the equivalent circuit
model whose circuit description code is R(C(R(RC))). This equivalent circuit uses the constant
phase angle element Q instead of the capacitance C in the second resistance-capacitance parallel
entries, and its circuit description code is R(C(R (RQ))). The results show that the model is more
reasonable, because the error is smaller when it is used to fit the impedance spectra of the sensor.

Abstract - Weighted criteria is one of the important precedures in decision making. Each of the
criteria has their own weights in predetermine the selection. It is normal practice in decision
making to weight the criteria based solely on positive evaluation to represent degree of
importance. However weights of criteria is possible to determine by considering two-sides
evaluation. This paper proposes a method to estimate criteria weights under conflicting bifuzzy
preference relations. The new preference offers an oppurtunity for decision maker to give
judgment for both positive and negative evaluations simultaneously. The preference relations
matrix is solved using the conflicting bifuzzy arithmetic averaging operator and score function.
The aggregation is utilized by normalization prior weights determination. A numerical example is
given to illustrate the proposed method. The ranking of the criteria is represented by the weights.
It seems that an application of a score function in conflicting preference is a feasible tool in
weights determination.

inventory decisions before the demand is realized. First, we establish that the supply chain can not
be coordinated with the buy back, revenue sharing, and target rebate and quantity flexibility
contract. Next, we show quantity discount contract can coordinate the supply chain and give a
special quantity discount contract. Finally, we present a contract called revenue and loss sharing
contract which mitigates the effect of shortage penalty loss and coordinates the decentralized

protocol in wireless sensor networks which are widely used for long-time monitoring. Our
protocol is designed for event-driven and ultra-low power sensor networks. Using dynamic sleep
scheme to save energy is one of the key problems in this kind of system. The basic idea is that,
when an event is apperceived by sensors, all nodes in the network use a value of grads to earmark
the location of an event, which is used for data searching expediently, and all nodes adjust their
sleep periods dynamically due to their grads. Simulations show that, our MAC protocol for
event-driven wireless sensor networks shows higher efficiency than exists approaches and is more
suitable for long-time monitoring.

Abstract— This paper proposes a new operation method for portable devices and controllers using
fingertip pressure. The proposed system provides multivalued, biaxial outputs according to the
fingertip pressure from two directions. Strain sensors are used to detect microscopic strains caused
by the fingertip pressure on the body of the portable device. For verification experiments, a
prototype consisting of a detection circuit with two strain gauges and a 32 bit MPU with an
aluminum body was manufactured, and various applications were implemented. The experimental
results indicate that the prototype system can output accurate linear data proportional to fingertip
pressure from two directions. With the proposed interface, the portable devices do not require a
specific area, thickness, or position for input buttons on their bodies.
Keywords- Fingertip pressure, strain gauges, biaxial input and output.

Abstract—This paper presents a design of residue amplification circuit (MDAC) used in the first
1.5-bit pipeline stage of an ADC, and the MDAC should meet requirements of a 100MS/s 14-bit
pipeline ADC with 1.8V supply voltage. In order to obtain the corresponding performance, the
circuits such as operational amplifier and bootstrap circuit are designed which could realize the
objective of high-speed and high-resolution. The gain-boost structure is used in the amplifier to
obtain the specified resolution, and an optimization between speed and power dissipation should
be carefully conducted as a high speed requires a large slew rate or trans-conductance which is
proportional to power dissipation. The design is implemented in the 0.18µm CMOS process with
9.6mW power consumption and the simulation results in Spectre illustrate that, the designed
operational amplifier could reach the fixed objective and the residue signal of MDAC could set up
completely in the specified time 3ns.

Abstract— Home appliances can be connected in a ubiquitous manner by communication
networks. In addition to the operation sensing of home appliances, appliance management via
sending control messages will be needed. The control operations include power adjustment of
home appliances and sampling rate change of a sensing device. It should be noted that control
messages differ from sensing data and the former generally require more reliability. In this paper,
we study the delay performance of control messages at MAC (Media Access Control) layer in the
network with shared communication media. The proposed approach can confine the delay
uncertainty of the control messages within a specified tolerant time for respective appliance.

Abstract—a real-time, interactive video distribution system on Internet for large-scale users faces
three bottlenecks: real-time performance, interactive performance and bandwidth pressure. This
paper, based on the approach to establish a Real-time Peer-to-Peer network (RTP2P) with the
minimum video data delay as the primary goal, and establish a hybrid framework of P2P and
centralized networks, argues that the goal of real-time, interactive video distribution system for
large-scale users is able to be achieved. The key technologies include: greedy scheduling
algorithm, push-pull scheduling model, and the hybrid network model. The test result proves,
through an online education system with 2000 simultaneous users, that the end user’s video delay
is within 10 seconds. Compared with the normal P2P video streaming system with the delay varies
between 30 to 120 seconds, Real-time P2P is far more close to C/S networks, the widely adopted
network in China, the high bandwidth cost of which restricts its promotion. In short, RTP2P is a
more real-time, lower bandwidth-costing network to distribute video stream, saving more than
90% of the bandwidth cost. This program is applicable to the field of large scale users’ video
real-time performance and interaction, such as online education, chat rooms, multimedia social
games, live broadcasting, etc.

Abstract—With the development of the virtual reality technology and Internet technology,
three-dimension display of e-commerce has become an inevitable trend. The virtual display
technology is studied by this paper, because there are some gaps of display in e-commerce sites.
With the example of phone display which is designed basing on Virtools, how the virtual reality
display technology is applied for e-commerce site is described.
Key words- e-commerce; virtual reality ; Virtools
E-commerce is an act of transactions in the Internet and has been a very rapid development.
Display and display of goods is an important feature of e-commerce sites. With the limitations of
HTML language, commodity display methods are often limited to use of pictures on display, and
to assist in the text description and so on, which can only provide dimensional effect, from one
side to see the product shape, so it is impossible to understand the product's features. So
consumers have little interest in the products, and hamper decisions of consumer purchasing,
reducing the success rate of business transactions in internet. The combination of e-commerce and
virtual reality is in favor of presentation of three-dimensional information .It resolves the problem
which the realistic constraints on the development of E-Commerce, and bring in unparalleled
advantage in the network marketing effect.

Abstract— Currently, most products are designed to support their users using them consciously. In
fact, there are four stages of learning according to the relationship of consciousness and
competency: 1) unconscious incompetence, 2) conscious incompetence, 3) conscious competence,
and 4) unconscious competence. The third stage is considered the most perfect due to users’
competency and consciousness whilst a task is being performed. As a consequence, products are
designed by using feed forward, a signal sent from products to users, to a different sense other
than the one engaged in a current task. This is deemed wholly suitable for users of the third stage.
However, after having continuously performed a task, users eventually proceed to the fourth stage,
that of unconscious competence user. Products designed to use feed forward signals at this point,
might not be the most effective means of alerting unconscious competence users.
This study, then examines whether feedback or feed forward is better suited - in terms of speed to alert user response to signals. The methodology of this study uses subject performance
measurement. Subjects are asked to perform two tests - the first was one normally done
unconsciously, that of simply seating oneself. The second task requires, through the performance
of a repetitive act, (that of moving two red beans per time using chopsticks) drawing away the
attention as much as possible, from subjects in their seats. The assumption is that subjects would
adjust their posture accordingly (draw nearer to the red beans) when improved concentration was
needed to move them and not to pay attention to whether they are seated correctly or not.
During the test, both feedback and feed forward signals alerted subjects to control distance
between their eyes and the beans themselves. Results reveal feedback was better in alerting
subjects when controlling distance and returning back to the original posture, in terms of speed of
response.
The explanation is that response to feedback signal happens immediately. With feedback, the
subject reacts physically at the body part, later sending a message to the brain explaining what has
just occurred. Meanwhile, response to feed forward occurs only after the brain has sent commands
to the body part it wishes to move. The objective of this study is neither to provide nor to confirm
the appropriate use of the feedback signal, only to establish certain factors and their intricate
relationship, which can be used to inform the design of feedback as a signal within products.
Feedback signals themselves cannot completely alert unconscious competence users; however,
kinesthetic ability of the tasks should be taken into consideration.
Keywords- Unconscious Competence User; Feed Forward-Feedback Control; Motor Skill

Abstract—One of the major problems in Mobile Grid environments is the optimal distribution and
replication of data files, in order to improve and maintain a high overall throughput of Grid jobs
that access files. A data replica replacement algorithm based on value model is proposed and the
arithmetic method to calculate replica value is introduced. This algorithm adapts to the high
variation environment in Mobile Grid environment. The value of a data replica reflects the usage
history of the cache and the variability of it. We construct a data replica value evaluation system
which makes those unstable or rarely used replicas first be deleted, when there is not enough
storage space during replication. Experimental results show that the proposed algorithm can obtain
better performance for grid tasks to access data replicas.

Abstract—This paper proposes an improved state-dependent Riccati equation (SDRE) attitude
control approach which is applied to an unmanned helicopter (UMH) through a multi-timescale
structure. To deal with inherent unstable internal dynamics, the flapping and rotational dynamics
of the helicopter are organized into a two-timescale nonlinear model. To overcome the problem
that a number of terms can’t be accounted in the SDRE design, we employ a nonlinear
feedforward compensator that is designed to match the vehicle response to the model used in the
SDRE design. To overcome the feedforward compensator’s disadvantage of being directly
affected by parametric disturbances, we improve the design method and add a proportion+ integral
(PI) controller. SDRE is solved by “ ” method. The simulation results show satisfactory tracking
performance of the designed control system.

Abstract—In this paper, we present a new Neighbor Sharing Selection based Agglomerative fuzzy
K-means (NSS-AKmeans) algorithm for learning optimal number of clusters and generating better
clustering results. The NSS-AKmeans can identify high density areas and determine initial cluster
centers from these areas with a neighbor sharing selection method. To select initial cluster centers,
we propose an agglomeration energy (AE) factor for representing global density relationship of
objects, and a Neighbors Sharing Factor (NSF) for estimating local neighbor sharing relationship
of objects. Then we use the Agglomerative Fuzzy k-means clustering algorithm to further merge
these initial centers to obtain the preferred number of clusters and generate better clustering results.
Experimental results on various data sets have shown that the NSS-AKmeans was very effective
in automatically identifying the true cluster number as well as producing accurate clustering
results.

high speed OFDM technology receives increasing attentions in mobile communication.
Modulation programs are designed with VHDL based on the principle of OFDM in the paper. First,
after OFDM fundamental is introduced; two main advantages are obtained via discussing
spectrum utilization ratio of OFDM. Then, from the results of VHDL simulation, the realization of
baseband operations, such as interleaver, subcarrier modulation, IFFT and adding CP, are
presented. Finally, implemented programs are validated on the actual implement system.
Experimental results indicate that setup time corresponding to transmission velocity is only
71.05µs and steady time is approximately 6 times as setup time, that is, not only achieving the
high speed transmission, but also supplying adequate modulation time.

ontology heterogeneity in distributed environment which can hinder the inter-operability of the
services by using ontology to describe Web services and merged ontology can provide a good
basis for the inter-operability of services. To solve this problem, firstly a framework for
multi-mapping based ontology merging systems (MMOMS) is proposed, and the functions and
working processes of its six composition modules are fully described. Secondly, the compound
strategy to merge ontology mapping results is set forth in detail. Thirdly, 5 rules for ontology

Abstract—A novel video smoke recognition method based on optical flow is presented. The result
of optical flow is assumed to be an approximation of motion field. The method is proposed as
following, first, moving pixels and regions in the video are determined by a background
estimation method. Then, a pyramidal implementation of the Lucas Kanade feature tracker is
proposed to calculate the optical flow of regions determined by the first step. And the average and
variance of the corner points’ optical velocity are calculated which we call optical flow features
and use to differentiate smoke from some other moving objects. Finally, examples consisting of
features extracted from sequences of off-line videos are collected for the training of a
discriminating model. A prototype of back-propagation neural networks is introduced for the
discriminating model. Experiments show that the algorithm is significant for improving the
accuracy of fire smoke detection and reducing false alarms.

Abstract—Focusing on the problem of resource allocation under large-scale, distributed,
autonomous, heterogeneous and dynamic environments in grid computing, a heuristic algorithm
combining fuzzy clustering with application preference is proposed. Fuzzy clustering method is
applied according to a group of features, which describe the user’s application preference, to
realize reasonable pre-classification resource. Then a resource is chosen according to the synthetic
evaluation value, which can make the user’s target utility maximized. There is no need to search
every resource at each scheduling step. Therefore, the cost on choosing the resource to execute the
current task is reduced significantly. Experimental results show that the bigger the target system,
the more efficient the algorithm is, and the more satisfactorily the application preferences of users
are met. Furthermore, since resources are classified by different application preferences, this
method can also avoid heavy loads concentrating on only a few resources so as to improve load
balance in grid environments.

Abstract—Wavelet multiresolution analysis allows us to detect edges at different scales, also to
obtain other important aspects of the extracted edges. However, due to the usual two-dimensional
tensor product, wavelet transform is not optimal for representing images. The main problem in
edge detection using wavelet transform is that it can only capture point-singularities, and the
extracted edges are not continuous. In order to solve that problem, we propose a new image edge
detection method based on the contourlet transform. The directional multiresolution representation
Contourlet takes advantages of the intrinsic geometrical structure of images, and is appropriate for
the analysis of the image edges. Using the modulus maxima detection, an image edge detection
method based on contourlet transform is proposed. To suppress the image noise effect on edge
detection, the scale multiplication in contourlet domain is also proposed. Through real images
experiments, the proposed edge detection method’s performance for the extracted edges is
analyzed and compared with other two edge detection methods. The experiment result proves that
the proposed edge detection method improves over wavelet-based techniques and Canny detector,
and also works well for noisy images.

Abstract-KNN algorithm is particularly sensitive to outliers and noise contained in the training
data set. In this paper, we use the reverse cloud algorithm to map the training samples into clouds.
Each attribute is mapped to a cloud vector. Reverse cloud algorithm is not sensitive to the noise on
data sets and it can eliminate the impact of noise on classification effectively. By comparing the
similarity of clouds in the cloud vector, we can calculate the attributes weights. For those
attributes with a low weight of properties, we find out merger them to a new attribute which can
generate more significant attribute weight than original ones. We present a new KNN algorithm
based on Cloud Model and compare our algorithm with classic KNN algorithms and other
well-known improved KNN algorithms using 10 data sets. Experiments show that our approach
could achieve a better or at least a comparable classification accuracy with other algorithms.

Abstract—Organizing images into meaningful (semantically) categories using low-level visual
features is a challenging and important problem in content-based image retrieval. Clustering
algorithms make it possible to represent visual features of images with finite symbols. However,
there are two problems in most current image clustering algorithms. One is without considering
the choice of the initial cluster centers which have a direct impact on the formation of final
clusters, and the other is without considering the relevant features and assigning equal weights to
these feature dimensions. According to the two problems we propose a weighted features
algorithm. First, we use the labeled image samples to calculate the weight for each feature
according to the feature degree of discrete. These weighted features have been used to calculate
the initial cluster centers because they can well represent the cluster. Then, we use the weighted
features(based on the different image data set) algorithm to discard the irrelevant features and
reduce the feature dimensions through the whole clustering process. Experimental results and
comparisons are given to illustrate the performance of the new algorithm.

Abstract—In this article, we present an efficient connectivity compression algorithm for triangular
meshes. It is a face-based, single resolution and lossless connectivity compression method. This
method is an improvement on Edgebreaker. In the aspect of mesh traversing, we use adaptive
mesh traversing method to make Split operations as few as possible, which are burdens of the
compression ratio. In the aspect of Entropy encoding, a variable code-mode is well designed for
every operator in the operator series, which is the result of mesh traversing. Then a binary strand
can be obtained. And finally this binary strand is encoded by using adaptive arithmetic coding
method. The compression ratio of our algorithm is obtained when all the operators in the series are
encoded. In comparison to the previous best face-based encoding methods, our method can
significantly improve the compression ratio.

Abstract- The heat which electric furnace smelt iron alloy is needed is provided by electrode
extreme. When the position of electrode extreme is perfect, the power consumption and
productivity of production unit are in good state, so take control of electrode position is very
important. Electrode regulator system of ore smelting electric arc furnace is a nonlinear,
multivariate, parameter-time-varying system, its accurate mathematics model, inter-disturbance
and outer-disturbance are unstable. Designing PID constant current single close loop control
system is not so successful, so it puts forward a method of active disturbance rejection control
strategy. Design an electrode disturbance rejection control controller which is independent from
object model, and correct its parameter. The simulation experiment proves that when active
disturbance rejection control controller applies to the ore smelting electric arc furnace overshoot
of system regulation is little. Control effect is superior to traditional PID control, and it has strong
robustness. Disturbance simulation experiment proves that the disturbance rejection effect of
active disturbance rejection control system is perfect, and has strong inhibition force to the
disturbance.

With the development of technology, people have higher expectation of living, country has
invested a huge amount of money to the capital construction, especially to roads infrastructure. In
this situation, the roads infrastructure is developing fast, the highway mileage has enormous
increase and there is an increasing number of vehicles on the roads. However, the huge number of
cars raises problems of its own, there are more and more car thefts, lost and violations of rules
which are given serious attentions. The time which is spent on checking on the roads by the
department of traffic charge, check and police has been taken too much. Meanwhile, vehicles
overload problem is getting worse around the country. Because of the merits of high capacity,
large services and economy, public buses have become the main means of urban traffic. If the bus
which took lots of people had a traffic accident, the result would be serious. The main cause of
those serious accidents is overload, therefore, it is time to find some way to resolve this problem.
However, most departments take care of this problem in traditional way, such as manual judgment
and road checking. This traditional vehicle checking way has some faults such as leak checking,
false checking, and is a heavy work for vehicle checking people, so it needs to find a intelligent
mobile vehicle checking system to replace the traditional one. The new intelligent mobile vehicle
checking system is designed to meet this need.

Abstract— The ever-increasing complexities of IT systems is bringing great challenges to IT
management. Meanwhile, IT management is expanding beyond the traditional IT network
management and IT service management, and spreading to business service management. Existing
configuration management models for IT management solutions lack holistically presenting,
managing, and leveraging the IT logical entities related to business services (such as computing
services, application system, business system), relationships among these entities and traditional
IT physical entities (such as networks, computers, and processes). This research studies how these
entities interrelate to support business operations. We propose a business-oriented hierarchical
configuration management model for describing their relationships and this model’s application
for fault location and impact analysis. The model and algorithms form the basis of an advanced IT

Abstract—This paper introduces a novel scene recognition algorithm to perform reliable scene
recognition. Firstly, to construct the maximally stable regions, we exploit the maximally stable
color regions (MSCR) detector for improving the identification of stable regions. Secondly, each
detected region is processed properly by using the method of mathematics morphology. Finally,
the descriptor is computed by using the Principal Components Analysis (PCA) based scale
invariant feature transform (SIFT) descriptors, with the detected MSCR regions as input. Our
experiments demonstrate that this algorithm wins high recognition accuracy, is more robust to
image deformations and is both significantly more accurate and much faster than the standard
SIFT descriptor based algorithm. Also we compare our algorithm to the global appearance based
method, and show through experiments in both indoor and outdoor environments that our
approach performs better.

Abstract—To improve robustness of support vector regression (SVR) in nonlinear systems on-line
modeling, the relationship between outliers and the robustness of SVR is derived mathematically,
and a new modeling method using SVR is proposed. The relationship indicates that the effect of
outliers to SVR is decided by the training data distribution and the distance between outliers and
the support vectors nearest to them. Therefore, in the method, each component of the training data
is normalized into the same range, and then the components representing the system output are
compressed differently to change the training data distribution to reduce the effects of the outliers.
Meanwhile, a data updating criterion is presented to eliminate outliers. The method is applied to
multichannel electrohydraulic force servo synchronous loading system to predict the load output,
and the results show its effectiveness.

Abstract—Fingerprint image segmentation heavily influences the performance of fingerprint
verification systems. In recent years, some new methods have been introduced to the image
segmenting processing in order to get better disposal results. And most of the proposed algorithms
are based on threshold segmentation. In this paper, a novel approach is put forward to segment
fingerprint images based on multiple features. It makes use of local and global features to
determine block threshold adaptively without the experience. Meanwhile, the algorithm combines
the point level segmentation with the block level segmentation in order that it could be capable of
avoiding the appearance of the blocking effect of the foreground image edges at a low
computational cost. The performance of the new algorithm is evaluated on FVC2004 database.
Experiment results show that the proposed adaptive segmentation algorithm is effective and
robust.

Abstract—Fingerprint enhancement proceeds by fully utilizing the intrinsic properties of original
images to improve the ridges and eliminate the noises. Although Gabor filter is a classical
enhancement method, its function may suffer for the low-quality images due to the unreliable
orientation and frequency map estimated by conventional approach. In this paper, a new approach
has been proposed to estimate these parameters in an effective way. The local image is modeled as
a non-stationary signal and the technique of Short Time Fourier Transform(STFT) is applied to it.
Besides, to avoid the multi-step processing and inter-dependency, we extend the theory of
probability in mathematics to get the orientation and frequency simultaneously. The performance
of our approach is evaluated by the verification system of NIST and FVC2004 DB1_A database.
Experimental results show that our method can improve both the image quality and the accuracy
of fingerprint recognition.

Abstract—Current active transit signal priority (TSP) methods are based on real-time detection of
information, often with the green extension and early green to make bus pass through the
intersection as soon as possible. In this paper, according to domestic environment, applying active
transit signal priority in artery coordination system, using related transit priority principle and
parameter, can not only guarantee to execute transit priority, but also make the impact of transit
signal priority on coordination system minimum. Moreover, the active transit signal priority in
artery coordination system should consider the intersection with irregular phase, such as
overlapping phase to ensure traffic flow smoothly proceed. So this paper provides active transit
signal priority considering overlapping phase in artery progression (TSPOP), and this new green
decision model including green of overlapping phase, green of priority transit phase considers
green of overlapping phase in early green strategy can keep the same and in green extension
strategy can change as flow needs and transit priority request. Finally based on effect of the green
extension and early green on general traffic and bus traffic by simulation analysis, using delay of
the intersection, this thesis shows the result: TSPOP can reduce bus delay to transit priority and
better than transit signal priority without considering overlapping phase in the degree of transit
priority, and also can keep the delay of intersection little increase. Therefore, TSPOP in artery
progression is effective, which can provide a theoretical foundation and application experience in
practice.

time-stamping scheme and blocks the time synchronization frames until the actual time is equal to
the time in the payload of the frames. A preemptive mechanism is introduced to make sure the
time synchronization frames can be transmitted immediately when the actual time is equal to that.

adopts both filter and wrapper models of feature subset selection. In the first stage of the feature
selection, we use the filter model to rank the features by the mutual information (MI) between
each feature and each class, and then choose k highest relevant features to the classes. In the
second stage, we complete a wrapper model based feature selection algorithm, which uses Shepley

Experimental results show obviously that the HFS method obtains better classification
performance than solo Shepley value based or solo MI based feature selection method.

Abstract—When making trip mode choice, travelers often take account of personal private cost
such as travel time and money spent, while no considering external cost consisted of congestion
effect or pollutions of air and noise. There is a big difference between the external cost of different
travel modes in urban passenger transport, and the neglect of the external cost is to blame for
mode imbalance in Chinese urban passenger transport system. Expounding the connotative
meaning of urban passenger transport external cost, the effect of internalization of external cost on
urban passenger transport is analyzed. Based on the principle of disaggregate model of personal
trip mode choice, a modified Logit Model is established and the methods are given to
quantitatively calculate the effect of internalization of external cost. In the end, a numerical
example is given and discussed. The result shows that the internalization of external cost can
result in different proportions of vehicle and bicycle travelers turning to choose public transit.

Abstract—In the SaaS application, users can order corresponding software services from the
service provider according to their application needs and adjust their services content in use based
on the changes of the enterprise development, with strong elasticity and expansibility. However,
despite of so advanced concept of SaaS, there are still some problems in the SaaS field
constraining the wider use of SaaS. At present the composing model of SaaS, the development
method and the problem solving are all taken into account in some of the theories and applications,
but no one discusses the description of the SaaS model. As we all know, the model is also the key
to the construction of SaaS software development platform. The traditional modeling method
based on the workflow asks for understanding the operation processes of all aspects of business
for modelling personnel and needs the support of professional knowledge on updating and
maintenance of business processes. How to adopt a common way to describe it and make it
User-friendly search is a serious problem to be solved. Therefore, we propose SaaS service model
based on extended WSCL, and implement the modeling tool of SaaS service model. This paper
aims to develop a modeling tool to allow the modelling personnel to complete the modeling
process through understanding the business, and the system can automatically convert the state
diagram corresponding to the process into WSCL documents. The SaaS service modeling tools
can help developers easily model for the SaaS service, which makes the modelling process more
formalized and visualized, and then make it easy to communicate with users.

Abstract—Traditional group key generating methods using binary-tree performs efficiently when
adding or deleting nodes dynamically. However, when dealing with paroxysmal needs for group
key among multi-nodes in the Internet, their time complexity grows to O(Nlog2N). We propose an
improved group key agreement protocol based on Diffie-Hellman key exchange, which can reduce
the time complexity of this situation to O(N). It can largely reduce overlapping computation and
data packages’ sending times, and meanwhile, it remains binary-tree in each node, enabling it
efficiently to support dynamically adding and deleting nodes as well. And then the security of this
method is been analyzed and a basic idea for preventing MITM attacks is been presented.

Abstract—In this paper, we propose a real time pedestrian detection approach which consists of
two levels: coarse detection and further validation. First, partial stages of cascaded Adaboost
classifiers are adopted to detect the upper bodies and generate candidate regions with a high

Abstract—Empirical mode decomposition (EMD) is a powerful tool for the non-stationary and
nonlinear signal analysis and has attracted considerable attention recently. However, one of
primary problems existing in the EMD is the mode mixing, which makes the physical meaning of
decomposition results obscure. The ensemble EMD (EEMD) is presented to alleviate the
shortcoming. The EEMD is a noise-added method and can extract the components with truly
physical meaning from the signal. Firstly, a simulation signal is used to test the performance of the
EEMD; compared with the EMD, the EEMD illustrates the superiority over the EMD. Then, the
fault diagnosis method based on the EEMD is applied to diagnose the faults of the gearbox with
multiple faults and successfully extracts the multiple faults information from the collected signal.
The results show that the fault diagnosis method based on the EEMD is a promising method for
the fault diagnosis of gearboxes.

Abstract—Conventional techniques are unfit for processing the non-stationary and nonlinear

non-stationary and nonlinear signal analysis and has aroused wide concern recently. However, one
principal shortcoming occurring in the EMD is the mode mixing, which makes the physical

(EEMD) is proposed to improve the decomposition results from the EMD method. Firstly, a
simulation signal is employed to test the performance of the EEMD method, which demonstrates
the superiority over the EMD method. Next, the EEMD method is applied to analyze the signal
captured from the deck of the WZ12-1 platform and successfully reveals the reason causing the

method for the fault identification of the offshore platform.

on the Principal Components Inverse Transformation to obtain the fusion image; The Wavelet
Transformation chooses high- frequency and low-frequency to carry on inverse transformation
after decomposing the panchromatic image and multi-spectra image with some wavelet. In this

components and by taking the method of Wavelet Reconstruction, it is useful to reconstruct the
principal components with high-frequency of the panchromatic image of IKONOS and the
low-frequency of Multi-spectral image; Then obtain the final fusion image by taking the method
of Principal Component Inverse Transform; Combining with the way of visual interpretation and
the rule of information entropy and spectral correlation coefficient, we get a good result, the
amount of fusion image’s information is 7.4875, and the correlation coefficient is 0.8619.
Compared to a single method, the spectral information and resolution have been improved; the
result shows that, the method of combining with Wavelet Transform and Principal Component
Transform merge their own advantages and make up the disadvantages, the fusion image not only
improves the spatial resolution of the original image, but also retains the relatively high spectral
resolution, it will be propitious to the further extraction and processing of the remote sensing data.

Abstract—Due to the lack of widely stable and reliable water quality parameters on-line
instrumentation, it is difficult to implement closed-loop control of water quality and optimize the
operation for wastewater treatment plant. In this paper, a nonlinear dynamic soft-sensing
multi-model based on PLS is proposed to solve the problem of multi-variable, non-linear and

variables easily received as water flow and quality, the dissolved oxygen and oxygen aeration. The
methodology integrates dynamic ARX with Fuzzy C-means identifies operating conditions of
time-varying and uncertainty in the wastewater treatment process. NNPLS is used to establish a
number of non-linear model in different operating conditions and the whole non-linear system.
The proposed method is applied in soft-sensing of effluent quality component concentration in
wastewater treatment plant. Simulation results indicate that the method which establishes a
multi-variable model of water quality indicators is more precise than traditional linear PLS model.

This method is based on the author’s proposed hierarchical, lane-oriented 3D road network. The
key to implement contextual routing and navigation is to adopt cognition-based hierarchical
routing strategy and the view-based multi-scale navigation strategy. The two strategies enable
users routing on roadway centreline, carriageway or lane and provides 2D, 2.5D and 3D
communicating based on user defined context. A prototype is also developed in the VGEGIS
system and the experimental results have confirmed the effectiveness and efficiency of the method.
The paper will provide a contribution to flexible location-based services by innovatively
considering the hierarchical knowledge of the road network system and contextual visualization
needs.

Abstract—Density-based clustering algorithms, which are important algorithms for the task of
class identification in spatial database, have many advantages such as no dependence on the
number of clusters, ability to discover clusters with arbitrary shapes and handle noise. However,
clustering quality of most density-based clustering algorithms degrades when the clusters are of
different densities. To address this issue, this paper brings forward a clustering algorithm based on
characteristics of density distribution--CCDD algorithm. Firstly, it divides data space into a
number of grids. Secondly, it re-divides data space into many smaller partitions, according to each
grid’s one-dimensional or multi-dimensional characteristics of density distribution. Finally, it uses
an improved DBSCAN algorithm, which chooses different parameters according to each
partition’s local density, to cluster respectively. The experimental results show that CCDD
algorithm, which is superior in quality and efficiency to DBSCAN algorithm, can find clusters
with arbitrary shapes and different densities in spatial databases with noise.

Abstract—SaaS is a new delivery model for the software development and application. Providers
tend to make their SaaS products achieve higher level of maturity, serves more people, satisfy
more different individual requirements, while maintaining efficiency and flexibility. This paper
introduces a new SaaS application model called SaaS with tenancy agency. It adds two new layers:
tenancy process layer and tenancy agency layer, to traditional SOA architecture. First, the system
proposed in this paper splits the business process into unified elements, and handles these
elements in the same actuator. The actuator focusing on repeated work reduces processes
switching time and promotes efficiency. Second, the system combines these elements to tenancy
processes to achieve customization of the process. Third, the system sets one tenancy agency for
each group of tenants with similar requirements. In such architecture, agencies avoid being too
huge and work with noninterference. Platform has been made to produce and run SaaS in this
architecture. SaaS with tenancy agency is proved to be feasible.

Abstract—With the constant development of numerical control technology, the expansion of CNC
(computer numerical control) system function is restricted with the interpreter lacking in
universality and expansibility. In order to deal with this problem, a new model of interpreter was
proposed based on the analysis of NC (numerical control) program basic format. The model is
consisted of a NC program rules module and a processing module which includes a lexical
analysis sub-module, a syntax analysis sub-module and a machining command converting
sub-module. The legal word table and the machining function definitions table in the NC program
rules module assist the processing module to interpret the NC code. It is very pivotal for the
interpreter to be expansible that the CNC system developers can easily modify the NC program
rules module and other sub-modules in accordance to different functional requirements. The
design process of every module was expatiated and an interpreter prototype was developed based
on this mechanism, which verified the validity of this proposed approach.

Abstract—Based on the theoretical research and actual developing status of artificial intelligence
and expert system, this paper discusses several issues in the development of criminal investigation
expert systems (CIESs). In particular, we focus on an extension decision support system (EDSS)
which employs domain knowledge of recidivism in the crime analysis system. Using the elicited
domain knowledge, the EDSS tool uses deductive reasoning techniques to make inferences and
provide suggestive courses of action to support the investigatory functions of police, attorneys, or
probation officials. In this paper, we present an experience mapping intuitive inversion principle
(EMII), and we describe the rationale for developing the CIESs, why we focus on the criminal
analysis system, the methodology for eliciting EDSS domain knowledge and experience, and a
scenario of what we are implementing as a proof of intuition learning system. A series of
elicitation sessions which epitomize the EDSS have been discussed in the paper. After presenting
an overview of the system and the major research choices, we describe in detail the system’s
modules and present examples of its potential use.

Abstract—Unascertained theory and method are mathematical tool to deal with uncertain
information,which has rigorous logic. Traditional unascertained evaluation model determines
index weight by information entropy method usually, in which the weight value is more
objective, but information entropy method can’t express the knowledge and experience of experts
and the opinion of decision makers,and sometimes obvious deviation may exist between the
weight by entropy and the actual important degree,and even may lead to incorrect weight.This
paper introduces the analytic hierarchy process to modify information entropy,and establishes the
unascertained measure model basing on modified entropy weight.The model combines the weight
determined by experts and by entropy weight to solve the index weight,which gives a
comprehensive consideration of subjective and objective factors,and the method can improve the
accuracy of weight value and the reliability of evaluation results.

index as a performance index is studied. Control structure selection or the input-output pairing
problem is a key step in designing decentralized controllers for multivariable. The Relative Gain
Array (RGA) is an important tool for the control structure selection procedure. In this study, RGA
is calculated and decentralized minimum variance controllers are designed for each feasible
pairing. The MV performance index will be calculated from the closed loop transfer function
using the markov parameters. It is shown that the value of the MV index can propose an
input-output pairing that leads to minimum output variance. Several simulation results are
provided to show the main points of the paper.

Abstract—A Java3D virtual scene includes not only 3D models but also other elements. To
operate Java3D virtual scene as a whole in object-relational databases, a persistent scheme based
on Hibernate was used to persist Java3D virtual scene in Oracle. According to the tree structure of
Java3D virtual scene, 8 persistent classes and their bi-directional associations were created
through Hibernate Object/Relational Mapping and association mappings. The 3D models were
stored and modeled in Oracle 11g Spatial. Two custom java classes to map SDO_GEOMETRY
data type of Oracle 11g Spatial were also developed to solve the problem that Hibernate does not
provide support for mapping this type at present. The object-oriented 3D queries can be used in
the persistent scheme, including Shap3D queries, partial Shap3D queries, attribute queries and 3D
spatial queries. The developed 3D spatial queries supporting Oracle 11g spatial functions such as
SDO_RELATE,
SDO_WITHIN_DISTANCE,
SDO_FILTE,
SDO_INSIDE,
SDO_ANYINTERACT and SDO_NN can be executed through Hibernate Query Language and
Query by Criteria. The object-oriented 3D operations for the Java3D virtual scene objects can be
effectively executed in Oracle through Hibernate persistent technologies.

Abstract—With the wide use of web services over the world, an effective and efficient search
engine becomes necessary. In this paper, we analyzed the limitation of search method using
traditional UDDI, and make it in IR-style and take advantage of approximate string matching.
Motivated by the feature of WSDL files which define the interfaces of web services, we make
operations defined in WSDL files which compose web services as the base units for searching and
organize all information of operations and corresponding components as documents, which will
facilitate IR-Style keyword searching. In order to improve the precision of searching, we enable
users to specify weights in their queries. By defining our ranking function, we sort all the results
and present top n ones to users. We also build inverted indexes on operations and corresponding
documents to improve query efficiency. In addition, we carry out simple semantic analysis on
WSDL files to acquire better accuracy. At last, not only have we tested the efficiency of query
after introducing approximate string matching, but also have we verified the effectiveness of the
query results.

Abstract—The paper presents a novel adaptive neural-network based nonlinear model predictive
control (NMPC) methodology for hybrid systems with mixed inputs. For this purpose an online
self-organizing growing and pruning redial basis function (GAP-RBF) neural network is
employed to identify the hybrid system using the unscented kalman filter (UKF) learning
algorithm. A receding horizon adaptive NMPC is then devised based on the identified GAP-RBF
neural network model. The resulting nonlinear optimization problem is solved by a genetic
algorithm (GA). The performance of the proposed adaptive model predictive control methodology
is illustrated on a motorboat simulation case study.

Abstract—To explore brain areas involved in Boolean arithmetical computation, functional
magnetic imaging (fMRI) was performed on college students during performance of Boolean
calculation tasks. For the Boolean arithmetical problems relative to number-processing tasks,
results for all twelve subjects revealed bilateral activation in occipital cortex (areas 17 and 18),
frontal cortex (areas 6, 8, 9 and 46), and sub-lobar areas. Other simultaneously activated regions
included the left inferior parietal lobule, postcentral gyrus and superior parietal lobule. Areas
activated by the Boolean mathematical problems associative with the number-processing in
fronto-parieto-occipital network. These results confirm some existing hypotheses regarding the
cortical network of arithmetic processing, invite acquisition of complex mental problems, and
suggest basal role for complex mathematics.

Abstract— Fault tolerant manipulators maintain their trajectory even if their joint/s fails.
Assuming that the manipulator is fault tolerant on its trajectory, fault tolerant compliance
manipulators provide required force at their end-effector even when a joint fails. To achieve this,
the contributions of the faulty joints for the force of the end-effector are required to be mapped
into the proper compensating joint torques of the healthy joints to maintain the force. This paper
addresses the optimal mapping to minimize the force jump due to a fault, which is the maximum
effort to maintain the force when a fault occurs. The paper studies the locked joint fault/s of the
redundant manipulators and it relates the force jump at the end-effector to the faults within the
joints. Adding on a previous study to maintain the trajectory, in here the objective is to providing
fault tolerant force at the end-effector of the redundant manipulators. This optimal mapping with
minimum force jump is presented using matrix perturbation model. And the force jump is
calculated through this model for single and multiple joints fault. The proposed optimal mapping
is used in different fault scenarios for a 5-DOF manipulator; also it is deployed to compensate the
force at the end-effector for the 5-DOF manipulator through simulation study and the results are
presented.
Keywords-component; Redundant Serial Link Manipulator, Fault Tolerance Compliance,

Abstract—The direct torque control (DTC) technique has been widely used as a control strategy
for motor drive system. High torque ripple is a major problem when the motor is running at low
speed in DTC system. By analyzing the causes of torque ripple, it is can be found that the change
of the speed error signal is a good indicator to determine the situation of motor torque ripple. In
this paper, a DTC strategy with a fuzzy logic controller has been proposed. The inputs of the fuzzy
controller are the speed error signal and the change rate of current signal. The output is
incremental value of the torque hysteresis amplitude. Dynamic adjustment of the torque hysteresis
amplitude is the ultimate goal. The simulation results show that the DTC system with hysteresis
amplitude adjustment fuzzy logic controller can reduce the pulsation of the motor torque and flux,
and improve the performance of low-speed operating conditions.

Abstract—The two given gray images are preprocessed, including filtering image processing, on
the fault slice image binarization segmentation processing and image of the two distribution
centers. Mathematical morphology is used to acquire the contour of the interpolated image. Then,
the corresponding points are identified respectively in the two images through calculating the
relation between the arbitrary point of contours and the focal point of the angle. If the grey value
of both of the corresponding points are close to each other, linear interpolation is used to calculate
the grey value of the interpolated point. But if the two corresponding points have distinct grey
value, a method to calculate the interpolated point’s grey value is presented. Once all point’s grey
value are acquired, the final interpolated image is accomplished. The experimental results show
that this new method is effective.

Abstract-Software reliability growth models (SRGMs) based on the non-homogeneous Poisson
process (NHPP) are quite successful tools that have been proposed to assess the software
reliability. Most NHPP-SRGMs assume the detected faults are immediately corrected, but it is not
the case in real environments. In this paper, incorporating the testing coverage, considering
imperfect debugging and correcting time lag, we propose an improved NHPP-SRGM.
Experimental results show that the proposed model fits the failure data quite well and has a fairly
accurate prediction capability.

Abstract—This paper employs Genetic Programming (GP) with individuals of tree structure to
form empirical formulas in order to track the dynamic pattern of the moving average curves of
stock prices. We find that our method tracks the 60-day moving average better than other shorter
period averages. In order to minimize the effects of noise and other random events impacting on
the markets and maximize the effective information abstracted from the origin data, two
comparable data preprocessing methods for turning points are proposed to cooperate with GP for
more stable long & mid-term dynamic analysis and prediction. We use either discrete data with
fixed time intervals as long as 120 days or data at local extreme by FFT. So, the formula finding
system tracks the next turning point with the information of several previous turning points.
Simulations show that our method to track and predict long & mid-term change trend of stock
price is practical.

Abstract—Based on the balance theory of static electric field and CCD image forming features,
the internal principle of image forming is analyzed. A new algorithm for image space resolution
enhancement is presented. With this algorithm, the interpolation function can be adjusted
automatically with electrical potential difference of the adjoining pixels and its energy zone, by
means of which, the image can be magnified self-adaptively. Particularly, this algorithm takes into
consideration of the effects of each color vector on image’s interpolation. Therefore, marginal
vagueness, keystone distortion and distinct artifacts brought by traditional methods are overcome,
and color distortion brought by separate disposal of the color individually is also mitigated. Gray
image and color image are tested separately, and the test results show that with not only the image
quality is improved, but also clear margin and contour information is kept with this algorithm.

Abstract—Since the homogeneous charge compression ignition (HCCI or CAI) was put forward,
different manners were adopted to realize HCCI combustion with gasoline and ethanol. However,
each combustion mode could only work in a narrow operation region. In order to put the HCCI
modes into practice, the researchers suggested that the engine operated in more different HCCI
modes and operated in conventional combustion mode (SI、CI) in others operation conditions,
which was called hybrid combustion mode engine. In this paper, HCCI combustion was achieved
in a modified single cylinder mass production engine through preheating the intake charge and
trapping residual gases. Three modes of trapping residual gases were realized by a newly
developed full variable valve timing system controlled by electronic system. The transition
smoothness was improved by applying the strategy in which the fuelling consumption was
compensated. Due to the cycle-synchronous control of valve timings, injection and ignition
offered by the control system, transitions between the HCCI modes and SI operating mode can be
realized without misfire or negative torque response. In order to control the HCCI combustion
modes, the internal EGR strategies were studied by GT-POWER coupled with CHEMKIN.

Abstract—In QoS routing for wired networks, multiple path routing is popularly used. Because of
excessive routing overhead, algorithms are not well suited for MANET networks. The IEEE 802.3
DCF standard allows for the use of multiple channels available at the physical layer, by improving
the capacity of MANET networks by using multiple channel interfaces, a dual channel routing
(DCR) scheme is introduced that proactively maintains all nodes’ location information based on
periodic exchanges of these information in one channel. The location advertisements are
distributed to all nodes in the network. The resulting replicated distributed database represents the
entire network topology. Every node uses this connectivity map to calculate the shortest path to
every other node. Then, source transmits data packet in another channel. This traffic distribution
efficiently utilizes available network resources and prevents nodes of the route from being
congested in heavily loaded traffic situations. DCR is a hybrid proactive/reactive scheme. Because
there is no interference between two channels, the results of simulation show that the scheme can
improve networks performance.

Abstract—In the network control system (NCS), stochastic network time-delay makes the system
performance reduction and even instability. For the issue of compensation for network time-delay,
this paper launced a switching control strategy based on the building of switching model of the
NCS, which means to switch to a different controller according to the different intervals where
network time-delay fall into. When the time-delay is less than a sampling period, the LQG of
optimum control algorithm should be used with its good real-time. On the contrary, when the
time-delay is larger than a sampling period, an improved and rapid GPC algorithm is pointed out.
Finally, simulation result shows that this method has a good compensation effect to the network
time-delay and has a very good real-time performance.

Firstly, we analyzed the traditional sigma filter and showed its weakness in removing complex
noise while maintaining sharpness of edges. Secondly, the sigma filter was modified to
accommodate to image with complex noise. Then, to maintain the sharpness of weak edges, we
put forward a new method named grey center offset sigma filter (GCOSF). In GCOSF, canny
detector is utilized to detect regions containing edges. We adopt grey center offset value instead of

performs better than traditional sigma filter and several other filters by considering the effect of
noise removing and edge keeping simultaneously.

hand shapes of the key frames. Firstly, the hand area is segmented by active skin color model.
Then the hand motion trajectories are extracted with dynamic time warping(DTW) algorithm and
the key frame of video sequences is computed by frames difference. The hand gesture of the key
frame is considered as a static hand gesture. The feature of hand shape is represented with Fourier
descriptor and recognized by neural network. The combined method of the motion trajectories and
key frame is presented to recognize the dynamic hand gesture from unaided video sequences.
Experimental results show that the proposed approach is capable of effectively recognizing the
dynamic hand gesture.

Abstract—Clustering provides an effective way for data gathering in wireless sensor networks. In
practice applications, either the difference of energy consumed by sensor nodes or node
redeployment leads to the energy heterogeneous networks. This paper proposes a new distributed
Low-Energy node Protection Time-driven Clustering algorithm (LEPTC) for heterogeneous
wireless sensor networks, in which nodes are initialized with different energy levels. This new
approach aims at guaranteeing more uniform energy consumption of the nodes and prolonging
their lifetime. In LEPTC, cluster head selection is primarily based on the residual energy ratio
between a node and its neighboring node with lowest energy. As a result, a node with higher
residual energy around the low-energy node will produce a shorter time for cluster head
competition and hence have more chance to become a cluster head. So LEPTC can better handle
the heterogeneous energy capacities. Moreover, LEPTC adopts a multi-hop data transmission
manner for the “forced cluster heads”. Simulation results show that LEPTC outperforms some
existing clustering methods in terms of the network lifetime and the network data capacity in
energy heterogeneous networks.

Abstract—Feature matching is an important way of network intrusion detection system. With the
increasing of attack types, rule database becomes more and more larger and the course of
matching also becomes increasingly complex, which makes IDS easily to lose packets. For the
problem above, two kinds of signature customization methods which based on open ports and
CVE number are designed in this paper. These methods integrate the IDS and vulnerability
scanner, help the misuse NIDS to select appropriate signature for the protected host and eliminate
unnecessary signature matching through not modifying too much programs and setting the values
of NIDS. Some experiments have been done on testing the integrated system. The results show
that IDS can reduce the detection rules, useless alerts and improve detection efficiency after

Abstract—A non-linear image enhancement algorithm called Adaptive Color Restoration and
Luminance MSR Based Scheme for Image Enhancement (ACRL_MSR) is presented in this paper
to improve the visual quality of color images under poor lighting condition. The Red, Green,
Blue(R, G, B) color bands are enhanced by adjusting luminance which is automatically enhanced
to a proper range based on Human Visual System (HVS) via the adaptive parameter. At the same
time the percentage of R, G, B in three bands of the output images is almost as same as the original
one to prevent color distortion. The color bands in dark/shadow zones are enhanced partly by
luminance and partly by their original color values to make these areas more colorful and natural.
The new algorithm is observed from the experiment results, which produces more natural and
vivid color than those by MSRCR and LB_MSR.

Abstract—Traditional single next-hop routing has been unable to meet the needs of the increasing
network applications。Based on multi-hop routing mechanism, this paper proposes a multi-output
Switching fabric and dual pointer maximum-weight-first scheduling algorithm. On the basis of
distinguish queuing, the algorithm uses dual pointers to schedule the single output and
multi-output packets to achieving distributed scheduling and dynamic matching. Simulation
results show that the switching fabric has better delay performance under multi-next-hop routing.
The algorithm guarantees throughput and delay performance, meanwhile reducing implementation
complexity and improving the processing speed of switching fabric.

Abstract—To effectively avoid congestion and take full advantage of bandwidth inside a network,
routing optimization is needed for path selection over a set of equal-cost-multi-paths. In this paper,
a Link-Criticality-based ECMP routing optimization algorithm is proposed. As the traffic in the
network overlaps on some links, LCER selects the path with least link average utilization and hops
for the ECMPs. As compared with the existing traffic splitting algorithms, LCER provides a
network-wide load balancing performance, no packets arrived out-of-order, and the lowest average
end-to-end packet delays. Although additional expected bandwidth, based on measured daily
traffic profiles or service-level agreements, is needed by LCER, we argued that the extra
complexity incurred is marginal.

Abstract - The start-up drift of four frequency differential laser gyro is of great importance in the
fast launching occasions like missiles and fighter plane. This paper studies the characteristics of
startup drift and presents two kinds of compensation methods. Based on the traditional mathematic
model in terms of temperature, temperature changing rate and temperature gradient, the software
compensation is done with the drift data. From the analysis of the physics mechanism of start-up
drift, the hardware compensation is realized by adopting the corresponding technologies to control
the specific physics parameters’ thermal changes which directly cause the start-up drift.
Experiments show that software compensation is of little use while hardware compensation is
more suitable and effective.

Abstract—The paper proposes an improved ant colony optimization algorithm. This method first
designs two fuzzy controllers to optimize three parameters . Then it establishes a dynamic
searching window for ants and chaos information are added when near-neighbour city table is
constituted in order to increase research speed in initial stages of algorithm. In addition, the
concept of active degree of city node is presented as future information to supervise ants to
construct solution and update pheromone. Finally a new evaluation criterion is produced to
distinguish where paths are excellent or not. So the strategy not only conquers the weakness of
easily running into local optimization while making route optimization, but also enhances efficient
convergence of ant colony optimization algorithm. Results of large numbers of computer
simulations demonstrate that this novel algorithm can plan optimal path rapidly in intricate three

Abstract—In a peer-to-peer network, file replication technology is widely used to reduce hot spots
and improve search performance. Most current file replication methods replicate files in all nodes
or two endpoints on a client-server query path. However, these methods either have low
effectiveness or come at a cost of high overhead. This paper presents an adaptive file replication
method based on dynamic community (ARDC) that addresses the issue of where replicas should
be placed. Simulation results demonstrate the efficiency and effectiveness of ARDC in comparison
with other approaches. It dramatically reduces the overhead of file replication, and yields
significant improvements on the efficiency and effectiveness of file replication in terms of query
efficiency, replica hit rate and overloaded nodes reduction.

Abstract
A hidden Markov model (HMM) is a statistical tool applied to model stochastic sequences. In an
ordinary HMM a hidden Markov chain named, the chain of states emits a sequence of
observations. In this model, given a state the emissions are assumed to be independent from each
other. However several researchers have already studied the dependencies between emissions. In
this paper a new approach for consideration of dependencies among emissions is presented. We
start with the use of the information of the left hand side of any emission and introduce a new
model. We then take the information of the right hand side of any emission into account.
Protein is one of the most important molecules in any living cells and the study of protein

Abstract—The focus of this paper is the security of industrial design images. An encryption
algorithm, based on the Logistic and the Henon maps, is proposed. The algorithm aims to ensure
the security of industrial design images, and uses chaotic iteration to generate the encryption keys,

image pixels. The algorithm enhances the security of the algorithm in that secret keys in the
encryption process are not only associated with the chaotic maps, but also to intermediate cipher
text. In experiments, the corresponding results showed the proposed method is a promising
scheme for image encryption in terms of robustness.

Abstract— Classical particle filter needs large numbers of samples to properly approximate the
posterior density of the state evolution. Furthermore, sample impoverishment is an inevitable
problem, which is a key issue in the performance of a particle filter. In this paper, a particle
filtering algorithm based on ant colony optimization (ACO) was proposed to enhance the
performance of particle filter with small sample set. ACO algorithm optimized the sample set
before re-sampling step. Target state estimation was computed according to the optimized samples.
Ant colony algorithm can effectively eliminate particle degeneration and enhance its robustness.
Experiment results demonstrate that the proposed algorithm effectively improved the efficiency of

remove the training data, which has no contribution to the classification. The remaining data are
used to complete the training work for SVM to obtain the optimal hyper-plane. Besides, the
parameter adaptive optimization algorithm has both increased the flexibility of parameter selection
for SVM and enhanced the convergence speed. In the end, derived from the comparison of testing
performance using the data set from the database of Statlog, the experiment result indicates that
the proposed algorithm can both shorten the training time and provides high accuracy and
excellent generalization, also it can keep the distribution of original data set at the same time.

Abstract: Feature selection plays an important role in the area of machine learning. Class Label is
often used as the supervised information for supervised feature selection algorithm while
constraints are rarely used. So, an effective feature selection algorithm with pairwise constraints
called Constraints Score was proposed. But its performance still is limited by neglecting the
correlation between features. In this paper we improve this algorithm by considering the
correlation between features and using SVM density estimation, mutual information to measure
the correlation and further eliminate the feature redundancy. Experiments show the effectiveness
of our improved algorithm.

Abstract—In the Internet, nodes are identified using IP addresses that depend on their topological
location. IPv4/IPv6 translation technology involves address mapping between IPv6 and IPv4
nodes and the methods used to translate protocols, where nodes are in their respective IP version
of network. The various IPv4 addressing mechanisms and addressing architectures are studied.
The detailed study reveals that IPv4 addressing mechanisms were proposed only when IPv4 node
roams in IPv4 home network or IPv4 foreign network. The study clearly reveals that IPv4
addressing in IPv6 network is not considered. This paper points out the need of IPv4 addressing in
IPv6 network and proposes a new addressing mechanism to obtain an IPv4 Care-of-Address in
IPv6 network which is referred to as P46A. The paper also presents a clear implementation
procedure in acquiring P46A and binding update registration with its Home Agent. In fact, this
mechanism could be immediately deployed. The main objective of the proposed model is to
permit IPv4 mobile users to roam freely in any network i.e., either into IPv6 based networks, be
connected with internet and get serviced besides roaming in IPv4 network.

Abstract—When braking on split-μ road, yaw moment and steering force of vehicle will be
produced because the braking force is different for two side wheels. In order to deal with this
problem, the modified independent control mode is widely applied, however, there also exits some
defects. Because the gap of the adhensive coefficient of both sides is uncertain while braking, if
the fixed modified coefficient is applied, it is difficult to keep vehicle direction stability and
shorten the braking distance simultaneously under different gap former mentioned. This paper
proposes a method named split-μ road identification. Compare the difference of slip integral of
front wheels to threshold values during a certain pressure state in order to identify whether the
vehicle brakes on split-μ road. According to the integral of slip from both side wheels and vehicle
deceleration, the control mode dynamically changes the modified coefficients of pressure.
Simulation results show that the algorithm can identify whether the vehicle is braking on split-μ
road timely and also can identify the friction difference between the two sides accurately. The
pressure regulation mode can regulate brake pressure appropriately and keep vehicle directional
stability and shorten braking distance simultaneously.
Keywords-antilock braking system; identification; split-μ road; simulation.

thus overcomes the defect of premature convergence. Example of gear reducer indicates that
compared with the exiting algorithms, CPSO gets the best result, thus certify the improvement of

Abstract—increasing transmission power is an effective way to improve real-time data delivery in
wireless sensor networks. On the other hand, increased power will also incur more interference
though it can improve the link quality to increase real-time communication. So there is a tradeoff
between interference and delay. In this paper, we consider a joint power control, scheduling and
real-time routing problem, try to find a converged transmission power that can satisfy the on-line
real-time data packet delivery and also we can achieve little interference by using TDMA

Abstract - This paper presents investigations into the development of hybrid control schemes
for trajectory tracking and anti-swaying control of a double-pendulum-type overhead crane
(DPTOC) system. A nonlinear DPTOC system is considered and the dynamic model of the system
is derived using the Euler-Lagrange formulation. To study the effectiveness of the controllers,
initially nominal characteristics following trajectory following (NCTF) is developed for position
control of cart movement. The controller design, which is comprised of a nominal characteristic
trajectory (NCT) and PI compensator, is used to make the cart motion follow the NCT. This is
then extended to incorporate input shaping schemes for anti-swaying control of the system. The
positive input shaper with different orders was design based on properties of the system. The
results of the response with the controllers are presented in time and frequency domains. The
performances of hybrid control schemes are examined in terms of level of input tracking capability,
sway angle reduction and time response specifications in comparison to NCTF controller. Finally,
a comparative assessment of the control techniques is discussed and presented.
Index Terms – Double-pendulum-type overhead crane, anti-sway control, NCTF control, input

Abstract--Existing mobile ad-hoc routing protocols are based on a discrete, bimodal model for
links between nodes: a link either exists or is broken. This model cannot distinguish transmissions
which fail due to interference or congestion from those which fail due to their target being out of
transmission range. A statistical network link model is introduced to represent the quality of the
link by a statistical measure of link performance. Because of dynamic topologies properties of ad
hoc network, each node can’t achieve the global information about other nodes in the whole
network. In order to define optimal routes in a network with links of variable quality, ad-hoc
routing is modeled as a sequential decision making problem with incomplete information. More
precisely, ad hoc routing is mapped into a multi-agent reinforcement learning problem involving a
partially observable Markov decision processes (POMDPs). A new routing protocol called SNL-Q
is proposed based on a combination of continuous (rather than discrete) model for links and the
POMDP model within the ad hoc network. Different scenario-based performance evaluations of
the protocol in NS-2 are presented. In comparisons with AODV and DSR, SNL-Q routing exhibits
improved performance in congested wireless networks.

proposed to solve the problem of “curse of dimensionality”, that is the states space will grow
exponentially in the number of features, and low convergence speed. The method can reduce state
spaces greatly and can enhance the speed of the study. Choose actions with favorable purpose and
efficiency so as to optimize reward function and enhance convergence speed. Apply this method to
the Tetris game; the experiment result shows that the method can partly solve the “curse of
dimensionality” and can enhance the convergence speed prominent.

ABSTRACT— The inherent torque ripple of brushless DC motor limited its scope of application.
In this paper, the state space model of system was derived from the mathematical model of motor
to generate the desired current. An optimal state feedback controller using the Kalman filter state
estimation technique was established aimed at ripple free torque control. An active disturbance
rejection control algorithm was proposed to compensate for the effects of input disturbance.
Experimental results are presented that these two algorithms working together are capable of
reducing the torque ripple effectively under the condition of constant torque load.

Abstract—The key resources of a flight include aircraft, cockpit crew and cabin crew. For
purposes of dispatching resources effectively, the three resources may be distributed independently.
If the initial flight of a flight plan is delayed due to bad weather or other factors, it may result in
the delays of the directly downstream flights that need to await its resources. If the delays continue
to spread to the lower downstream flights, it may result in large area delay propagation. In order to
predict the propagated delays due to awaiting resources, a flight delay prediction model with
consideration of cross-flight plan awaiting resources is presented. The downstream flight delays
caused by the delayed upstream flights in the same flight plan and the different flight plans are
both taken into account. First of all, business analysis and modeling is provided, then the
definitions of variables and algorithms are described, finally, the effectiveness of the model and
algorithm is proved through simulation computing.

Abstract—Many Semi-supervised learning applications require a feature selection method to deal
with the unlabeled samples. Traditional researches deal it either with the “filter-type” feature
selection mechanism, which may not work well for classification tasks or “wrapper” mechanism,
which need high computational cost. Here we proposed a new semi-supervised feature selection
method based on hybrid feature selection mechanism. Its principle lies in using Relief Wrapper
method to explore the usage of unlabeled examples, which will help for training classifiers. In
essence, it uses unlabeled examples to extend the initial labeled training set with the help of
classifiers. Extensive experiments on publicly available datasets and formal analysis show its nice
combination of efficiency and accuracy

Abstract—In this paper we deal with calculating sphere parameters (e.g., spherical center, radius,
and circularity) to detect the construction quality of spherical buildings. This procedure consists of
three stages: data collection, coordinates transformation, and sphere parameters estimation,
respectively. We first performed Matlab to create a sphere surface as the spherical building used in
analysis. We then picked up different points located on the surface to estimate the sphere
parameters. Finally we discussed the influence of points’ distribution and density on the accuracy
of parameters estimation. The experimental result indicates our approach with points evenly
distributed both in “latitude” and “longitude” can achieve centimeter accuracy.

Abstract—In this paper we deal with the ill-posed problems of whole-cycle ambiguities estimation
by damped singular value decomposition (DSVD). First, we presented a singular normal equation
matrix of whole-cycle ambiguities estimation, and then added synthetic noises to the right hand
side to create two “noisy problems”. Second, we performed DSVD in conjunction with some
parameter-choice approaches (e.g., the L-curve, generalized cross-validation (GCV) function, and
normalized cumulative periodogram (NCP)), to solve ill-posed problems under different noise
conditions. Finally, we also discussed the performance of these parameter-choice approaches. The
results indicate that DSVD is promising in solving ill-posed problems, and the selection of
regularization parameter has significant effect on the ambiguities estimation.

Abstract—In high performance computing environment in many fields, to finish a task requires
not only computing service, but also data service and all kinds of device services, which results in
different relation dependences and is very complex, however, job management systems such as
PBS, LSF, and Condor and so on, only support time dependence among jobs, and are short of
fault-tolerance and complete flow control. Workflow-based user environment for high
performance computing is successfully applied in railway survey, which not only benefits
construction and control of task flow, but also enhances all kinds of relation dependences and flow
semantics, especially for the work flow engine based on event model with checkpoint function.
It provides good reliability . Thus, workflow-based user environment for high performance

Abstract—Monitoring and response for emergency environments is a novel application area for
the deployment of wireless sensor networks. In this context, delay-bounded delivery and robust
routing is the essential operating criteria in order to ensure safe and timely response for emergency
scenarios. Existing routing mechanisms for wireless sensor networks are not well suited for hazard
situations, especially as they do not consider critical and dynamic network scenarios. In this paper,
a novel delay-bounded and robust routing protocol is presented. The protocol adapts to handle
dynamic emergency scenarios and works well with the routing “hole” problem. Theoretical
analysis and simulation results indicate that our protocol is well suited for dynamic emergency
scenarios when compared with other related work.

Abstract—In order to solve the problems of difficulty to determine the number of partitions and
rule redundancy in neuro-fuzzy system modeling, this paper presents a new approach based on
DENCLUE using a dynamic threshold and similar rules merging (DDTSRM). By introducing
DDT, which uses a dynamic threshold rather than a global one in merging density-attractors in
DENCLUE, our approach is good at determining the number of partitions because DDT does not
depend on input parameters. Additionally, the modeling performance is improved for DDT can
find arbitrary shape and arbitrary density clusters. After structure identification we merge similar
rules by considering similarity measures between fuzzy sets. Finally, BP method is used to
precisely adjust the parameters of the fuzzy model. For illustration, we applied DDTSRM to a
nonlinear function and Box and Jenkins system. Experimental results show that DDTSRM is
effective to solve the problems with a good performance.

Abstract—Cognitive radio has been recognized as one of the most promising technologies dealing
with the scarcity of the radio spectrum. In cognitive radio system, with spectrum sensing,
secondary users are allowed to utilize the frequency bands of primary users when the bands are
idle. Hence, how to accurately detect the idle frequency bands has attracted many researchers’
eyes. Energy detection is the common method for idle band detection. However, the improper
energy detection threshold setting can dramatically affect the performance of the cognitive radio
system. There are two types of errors in spectrum sensing: false alarm and miss-detection. The
lower probability of false alarm means more underutilized spectrum can be reused by secondary
users and the lower probability of miss-detection, the better primary users are protected. In this
paper, we propose a fast and accurate search method for optimal local energy detection threshold,
which can minimize the total errors in spectrum sensing. Simulation results show that our
estimated optimal energy threshold is consistent with the actual one.

Abstract—To capture a dynamic system with static reduction algorithm, the cost will enlarge a lot
for the repeated work. Moreover, the algorithm can not catch partial changes in the system. To
smooth this issue, a dynamic attribute reduction algorithm is introduced when the universe of the
system keeps the same and the condition attribute set is added. The concept, Flagged Matrix,
K-Flagged Matrix and ∑-Flagged Vector is defined and a reduction algorithm for dynamic
information systems is given based on distinguishable relation. This algorithm will use the new
added attributes and corresponding matrixes to correct and adjust the original attribute reduction.
To do the reduction for the dynamic systems, as the theoretical illustration and empirical analysis
turns out in this paper; the new added attributes are compared with the original attributes
considering the distinguishable ability using corresponding matrixes. Then evaluate the added
attributes are the core attributes or not, and determine whether the added attributes can replace the
original attributes or not. After that, a new reduction is got. This algorithm can figure out the
dynamic attribute reduction efficiently. For it will use matrix operation instead of logical operation,
the cost of this algorithm is significantly decreased.

Abstract—This paper deals with the application of least squares support vector regression
(LS-SVR) with radial basis function (RBF) kernel in dam crack forecasting. In the process of
LS-SVR, we performed the standard grid search and particle swarm optimization (PSO) to tune
hyperparameters of LS-SVR. The results demonstrate that our PSO approach can identify optimal
or near optimal parameters faster than the exhaustive grid search. Comparison with results from
stepwise regression was also included, to evaluate the reliability of applying such a PSO method
which avoids doing an exhaustive grid search. We found that our LS-SVR approach is promising
in dam crack forecasting, however it cannot be used to extract the crack contributed by water
pressure, temperature variation, and aging effect, respectively.

respectively time-varying smooth full state feedback law via state-feedback and observer approach.
Then, we demonstrate that the orig-inal system state is globally asymptotically stabilized to the
desired configuration with the feedback control law. Lastly, the effectiveness of the proposed
method is illustrated and validated by simulation results on a model ship.

the authors, they all had various limitations and disadvantages. First, models of some detect
methods are too complicated, and their process are too fussy. Second, the performance of some
detect methods could decline when the embed rate minish. Based on re-stegnography, the
detection of this paper’s algorithm extracts 109-dimensions features and trains SVM(support
vector machine) multiclassifiers to classify all kinds of stego images and cover images with very
high precisions (approximately 100%). Not only the model is very simple, but the performance is
all the same excellent when the embed rate minish.

Abstract—Clustering classifies data into homogeneous groups such that the objects in each group
are similar and the objects between groups are not similar. Cluster algorithms can be available in
many literatures. And among them, spectral clustering (SC) is one of the most popular and
appealing clustering methods because of its generality, efficiency and its rich theoretical
foundation. But SC algorithms need cluster number firstly and use the top eigenvectors of
some affinity matrix as the relaxed version of the cluster result which may have no guarantee on
the quality of the solution. In this paper, we explore an effective GA-based clustering algorithm
for unknown with special genetic mechanism. The feature of our proposed method is that the
can be determined as part of cluster process automatically and it can improve cluster result of SCs
in term of accuracy. Experimental results illustrate the effectiveness of the proposed method.

Abstract— We calculate the Hurst exponent H(t) of several time series by dynamical
implementation of a scaling technique: the detrending moving average (DMA). In order to assess
the accuracy of the technique, we calculate the exponent H(t) for artificial series, simulating
monofractal Brownian paths, with assigned Hurst exponents H. We next calculate the exponent
H(t) for the return of high-frequency (tick-by-tick sampled every minute) series of the Shanghai
stock market. We find a much more pronounced time-variability in the local scaling exponent of
financial series compared to the artificial ones. The DMA algorithm allows the calculation of the
exponent H(t), without any a priori assumption on the stochastic process and on the probability
distribution function of the random variables, as happens, for example, in the case of the Kitagawa
grid and the extended Kalmann filtering methods. The present technique examines the local
scaling exponent H(t) around a given instant of time. This is a significant advance with respect to
the standard wavelet transform or to the higher-order power spectrum technique, which instead
operate on the global properties of the series by Legendre or Fourier transform of qth-order
moments.

Abstract—The shader in the GPU are widely used to model coastal terrain, but the created terrain
are of great similarity and unable to embody the differences of coastal features. To overcome the
above disadvantage, we present a new modeling method for created terrain based on sketch map.
Through specifying the coastal features type, the proposed modeling method can create according
coastal terrain easily. In order to produce realistic looking scenes, we propose a method to
implement the reflection and refraction effect of water in the GPU’s shader. The method can easily
control the coastal effect. Experiments show that the result graphs are true to nature.

Abstract — In recent times, the majority of e-commerce applications are designed using
asymmetric cryptography to assure the authentication of the concerned parties. Conversely, an
increasing requirement for mobile devices has geared a shift towards mobile e-commerce
applications. This research work emphasizes that the existing authentication protocols, based on
RSA asymmetric cryptography are not suitable for such devices due to their confines in computing
power, memory capacity, key sizes and cryptographic support. For that reason, an efficient
protocol for resource constrained platforms that attain a level of security similar to the one
achieved by the protocols in use today is designed and implemented. This protocol is based solely
on Elliptic curve asymmetric cryptography and the results demonstrate that the performance
achieved is good in contrast to RSA.

Abstract—Situation assessment (SA) is one of the important processes in military decision. As a
component of battlefield data fusion and decision support, SA is not easy to be realized ideally by
using one particular technology in practice. Like any other complex military process, it requires
the cooperation of lots of information processing technology. This paper describe a mechanism for
constructing probabilistic models to represent and analyze uncertainties and assessing battlefield
state based on a hierarchical distributed fusion processing of incoming information which can help
commanders and analysts to model and assess the dynamic evolving situational state easily. We
adopted a hierarchy distributed DBN model which can process information hierarchically and
cooperatively through higher-level dynamic Bayesian networks and distributed lower-level
dynamic Bayesian networks. And a 3-layer distributed computation environment is also
introduced. The hierarchy distributed DBN can generate an accurate and efficient assessment of
the battlespace and suitable for military hierarchical organizations.

Abstract—Platform-based development is the dominant development method of enterprise
application, but the features provided by current mainstream enterprise application development
platforms are too abstract and lower-level, which focus on technical aspects rather than business,
to lead to a high degree of difficulty and heavy workload during the building of specific enterprise
applications. Other platforms might offer some better business-oriented features, but at the same
time they have strong industry limitations. This paper presents a novel general-purpose enterprise
application business infrastructure software platform, in which the technology complexity is
encapsulated in the bottom, so the technical ability requirement of the user that uses platform to
build specific enterprise application is reduced. Whether user can successfully build an enterprise
application through platform or not, is mainly depended on their cognitive level of the enterprise
business. Enterprise applications built upon the platform can agilely respond to the changes of
business. The efficiency and flexibility of the prototype platform built with the ideas and methods
have gotten an initial validation from the simulation construction of a certain civil aviation airport
prototype information system.

Abstract— Emotion is now recognized as a central element of human behavior, and thus it should
be embedded within the reasoning process when an intelligent agent or a robot aims to emulate
human reactions. Therefore, current research in AI shows an increasing interest in artificial
emotion for developing the human-like agent. Based on emotion psychology and artificial emotion,
this paper presents a behavior decision model of intelligent agent, the model consists of emotions,
motivations and behavior decision. The mapping relationship between exterior stimulates and
emotion is built by D-S evidence theory. And the model applies the markov decision process to
determine emotion states to behaviors. The model provides a valid method to the emotional agent
modeling and affective decision system.

new fault-tolerant capacity model is proposed to resist the cascading failures triggered by an
intentional removal of the edges with the lowest loads and a new measurement is put forward to
quantify the effectiveness of our model. Comparing with other models previously reported, our

Abstract—A Real-time and reliable detection of anomalies is an important and challenging task.
Unlike most detection methods based on the statistical analysis of the packet headers (Such as IP
addresses and ports), we propose a new nonlinear approach only using network traffic volumes to
detect anomalies reliably. Our method is based on the largest Lyapunov exponent and the
change-point detection theory to judge whether anomalies have happened. In details, the largest
Lyapunov exponents of normal and anomaly data fluctuate slightly respectively while those of the
overlapped data composed of them fluctuate greatly because the dynamic structure of data has
changed. Experimental results on network traffic volumes transformed from 1999 DARPA
intrusion evaluation data set show that this method can more effectively detect network anomalies
contrast to a linear method .

Abstract—Wireless sensor networks (WSNs) usually work under harsh environment, so high
packet loss rate is induced by the unreliable and error-prone wireless links. To cope with the
problem, a competition and cooperation based reliable forwarding protocol (CCRF) is proposed.
In CCRF, the characteristic of dense deployment of sensor nodes and broadcast feature of the
wireless channel in WSN are utilized. Specifically, adjacent nodes along the path spontaneously
constitute a receiving cluster in data forwarding and then data reception and acknowledgement are
executed by the means of cooperation among the cluster members to enhance data forwarding
reliability and to reduce energy consumption caused by redundant transmission. In the routing,
distributed fuzzy integral assessment algorithm is adopted, by which differentiated priorities of the
clusters along the path are allocated in accordance with the resource condition including
forwarding reliability, forwarding distance per hop and remaining energy and next-hop receiving
cluster in possession of optimal resource is dynamically selected through back-off competition to
achieve the efficient transmission. The NS2 simulation result further corroborate its superior
integrated performance compared with homogeneous protocols.

Abstract—In this paper, we propose a fast semi-supervised learning algorithm based on the
bisecting clustering. The key idea of the proposed algorithm is dividing data into two sub clusters
each time by using bisecting clustering and parts of the features of the data. The time complexity
of the algorithm is nearly linear to the data size. Numerical comparisons with several existing
methods for the UCI datasets and benchmark datasets verify the effectiveness of our method.

Abstract—Relevance vector machine (RVM) is a state-of-the-art technique for regression and
classification, as a sparse Bayesian extension version of the support vector machine. The selection
of a kernel and associated parameter is a critical step of RVM application. The real-world
application and recent researches have emphasized the requirement to multiple kernel learning, in
order to boost the fitting accuracy by adapting better the characteristics of the data. This paper
presents a data-driven evolutionary approach, called Genetic Complex Multiple Kernel Relevance
Vector Regression (GCMK RVR), which combines genetic programming(GP) and relevance
vector regression to evolve an optimal or near-optimal complex multiple kernel function. Each GP
chromosome is a tree that encodes the mathematical expression of a complex multiple kernel
function. Numerical experiments on several benchmark datasets show that the RVR involving this
GCMK perform better than not only the widely used simple kernel, Polynomial, Gaussian RBF
and Sigmoid kernel, but also the convex linear multiple kernel function.

Abstract—This paper introduces a novel semi-blind channel estimation algorithm based on
Orthogonal Procrustes (OP) approach for Multiple Input Multiple Output (MIMO) systems using
Orthogonal Frequency Division Multiplexing (OFDM) modulation. The presented joint estimator
is based on decomposition of channel matrix H as a whitening matrix R and a unitary rotation
matrix Q. The whitening matrix R can be estimated blindly based on the eigenvalue
decomposition (EVD) of the received signal correlation matrix, while Q has to be fed by using the
properties of the constrained OP estimator for an orthogonal pilot sequence. The estimation gain is
obtained by the power method with low complexity as it offers such optimum rotation matrices
which are parameterized a fewer number of parameters. Various numerical examples are
conducted to support the algorithms and analysis, and they demonstrate improved performance
up to 3-5 dB compared to exclusively training-based estimation.

Abstract
Regular flow nets, extended from Petri nets and YAWL, have been proposed as bases for modeling
web service behavior because of their abilities for dealing with cyclic behavior and data
dependences among services. However, the corresponding approach on how to regularize flow
nets into regular flow nets has not been given yet. So, in this paper we propose a methodology for
the regularization of flow nets. Firstly, we introduce concepts related to flow nets and regular flow
nets. Secondly, we define one pattern for each type flow net, and based on these patterns we can
get the corresponding regular flow nets of almost all of flow nets through regularization. Finally,
some special patterns that might not be regularized together with a particular example are
discussed.

Abstract—The problem of detecting moving targets which migrate between rang cells is
considered. The traditional MTD method can not effectively integrate the energy of targets,
because it integrates multi-pulse in the same range cell in a CPI. This paper introduces a novel
algorithm of coherent integration for moving target detection (MTCI), which is calculated along
the track of the moving target. A mathematical formula of MTCI algorithm is derived based on the
signal model of a moving target in Chirp Radar. The integrating results of MTCI and MTD
methods in the Gaussian white noise background are also compared. A Monte Carlo simulation
has been performed to evaluate the detecting performance of MTCI algorithm, and the detection
curves are also given.

Abstract—Multichannel fast QR decomposition recursive least-squares (MC-FQRD-RLS)
algorithms are well known for their good numerical properties and low computational complexity.
There are tow distinct ways to obtain the expended input vector, sequential-type method, and
block-type one. The latter one, despite exhibiting a higher computational burden as compared to
the former one, has some attractive features, e.g., suitability for parallel implementation.
Predistortion techniques for linearizing power amplifier (PA) nonlinearity with indirect learning
architecture (IDLA) are widely used. The benefit of the IDLA leaves unnecessary the assumption
of a model for PA, corresponding parameters estimation and inverse construction. In this paper we
present a new technique for predistortion using block-type MC-FQRD-RLS algorithm with IDLA,
in which the predistorter is constructed by simplified volterra model. Simulations results verify
that the proposed techniques have good convergence property.

Abstract—An adaptive media playout algorithm based on probability estimation is proposed to
reduce the video playout jitter and playout halt caused by buffer underflow. It adjusts the duration

Abstract: On the basis of the relative motion relations of the formation flight, UAV longitudinal
and lateral fuzzy controllers are designed to solve the multi-UAV formation control problem. The
relative positions between adjacent UAVs are controlled to meet the desired commands and
performance requirements. Q-Learning method, which is one kind of reinforcement learning, is
used to tune the corresponding parameters in output membership functions of fuzzy controller.

the steady state errors. Also, different conditions including coordinative turning, tense-loose shape
changing, shape sequence changing and collision avoiding are simulated with the formation

Abstract—Understanding user’ read and reply behaviors are important both for the study of online
social network properties and the modeling of information dissemination and trend prediction. Our
dataset is crawled from a famous Chinese BBS social network. By analyzing the read and reply
datas of users, we observe that distributions of discussion size and user participation level follow
the power-law distribution, agreeing with former empirical and analytical investigations. But the
distribution of user interest does not exhibit a power-law property. Statistics from hot posts show
that read and reply behaviors vary among different topic categories. For every 100 users interested
in a post, one or two of them in average would join the discussion. In addition, investigation
concerning time property of replies shows that decay functions with periodical fluctuations are
suitable to describe the short-term evolution.

Abstract—Hybrid in-band on-channel (IBOC) broadcasting system is a scheme of digital audio
radio, which could transmit analog AM and digital audio simultaneously. In IBOC systems,
broadcasters transmit signals within the allocated channel bands, thus the bandwidth assigned for
digital audio transmission is very limited. BICM can improve BER performance over Rayleigh
fading channels without bandwidth expansion, thus it is widely used in mobile-radio channels. It
has been found that by using BICM, an IBOC-AM broadcasting system can yield a better coding
gain. Turbo-BICM, the combination of turbo encoder and BICM, is known as a remarkable
scheme with high coding diversity and high flexibility. In this paper, an improved channel coding
scheme based on turbo-BICM is proposed to achieve better reliability compared with the
conventional IBOC system. Simulation results show that the proposed scheme can effectively
improve the receiving performance of an AM IBOC system. When BER is below 10-5, the
improved coding scheme can achieve more than 4dB code gains over Rayleigh fading channels.

Abstract—This paper proposes an improved channel coding scheme based on bit-interleaved
coded modulation (BICM) for in-band on-channel amplitude modulation (IBOC-AM). It can yield
better coding gains than traditional scheme over Rayleigh fading channels. Generally, BICM
embedded LDPC code for IBOC (BICM-L) has better coding performances than BICM embedded
convolutional codes for IBOC (BICM-C), which has been proved to be an advanced scheme.
However, there is a zone named blind-zone existing in the region of SNRs, where the performance
gains of BICM-L with high-order modulation are worse than BICM-C. To achieve an improved
performance, for the blind-zone， BICM-L is replaced by BICM-C in this improved scheme.
Simulation results confirm that, by using the proposed improved scheme, a better performance
gains up to 0.3 dB can be achieved for the blind-zone between 4 dB SNR and 5.1 dB SNR, while
an additional gains about 4 dB can be achieved in regions of high SNRs.

the traditional evaluation methods. In order to overcome these problems, grey interval relation
membership degree is applied in the field of human-machine interface evaluation in this paper.
The concept of membership degree is imported and integrated with grey relation analysis in the
method. By comparing the relation membership degree between the design schemes and the
reference schemes, including the ideal scheme and the negative ideal scheme, the optimal scheme
can be found. Based on the proposed method, a novel evaluation model of human-machine

Abstract— This paper proposes the position control of DC motor. Two methods are used for
position control, LQR method and feedback linearization. We show that these methods without
load torque are stable, but, when load is added to the motor's shaft, LQR and feedback
linearization can not make efficient input signal for reference tracking in output. To solve this
problem, we combined these methods and will show by using combined method, the position of
shaft tracks reference in presence of large torque. For validation of new controller, we compared
response with LQR and feedback linearization. Simulation results show stable response of new
method.

Abstract— The role of information technology (IT) in the business arena has continuously shifted
over the last decades, and it has become an important part of how companies manage and control
their resources. During the last years business computing has changed from these basic local data
administrative systems into international computer networks, and as the sophistication of the
computer systems increased, so did the investment cost. So, traditionally, companies tend to
perceive their IT-systems as costs, often due to IT being looked at as a support function. And user
satisfaction in IT usage is critical because this construct is often viewed as a surrogate for IT
success.
The purpose of this paper is to contribute to the body of knowledge about to what extent IT affects
the ability to solve accounting tasks. We will measure the impact of IT on user satisfaction and on
accounting information use.
The relationship between IT and accounting practices was investigated quantitatively using a
postal survey. The findings suggest that user satisfaction in IT usage, the use of accounting
techniques and accounting information increases with new IT investments.

Abstract—Efficient sensor node localization algorithm is a research highlight in the applications
of wireless sensor networks (WSN). An event information with few node location information is
meaningless in practical application. The number and density of nodes shared by
unknown-distance node pair are applied to establish close degree model in the paper. The close
degree model is also combined with the triangle similarity theory to propose a mathematical
model to calculate the distance of single-hop and multi-hop nodes. The simulation results show
that the normalized localization error of the improved algorithm is smaller than the conventional
DV-HOP algorithm.

Abstract—Our team developed a portable three dimension (3D) body measurement system based
on binocular stereo vision. By measuring the body using the system, the body scan line point
cloud is reconstructed. Because the surface properties, occlusions and accessibility limitations
cause scanners to miss some surface areas, leading to incomplete reconstruction and introducing
holes in the resulting models. In this paper, a simple and efficient method is proposed to fill holes.
Based on the characteristics of scan line point cloud orderly stored in computer, points that belong
to same scan line are fitted into a curve by cubic parametric spline function. Before that, the
overlapping points which are not accessible to fit curve are removed and data points that are so
dense to make computer poor efficiency are reduced. Because cubic parametric spline has C0, C1
and C2 continuity at each junction point, the filled points naturally transit to initial points and the
holes are disappeared. Then body model without holes whose points are even distributed is
constructed.

Abstract—Traditional algorithm for resource leveling optimization is based on the resource
allocation pattern which is conventional distribution, i.e. the amount of resource invested is
constant through the time when the leveling activity is underway. However, that assumption is
always incompatible with practical working pattern of resource. In practice, resource allocation
varies often with different features of activity and resource. The practical situation of multiple
resource allocation patterns in network is studied in this paper, and the logical relation and
resource constrains among activities under the condition of unconventional resource allocation
pattern is analyzed. Mean square deviation of resource is taken as an evaluation function for
evaluating resource equilibrium. Network schedule leveling optimization model based on
unconventional allocation pattern of resource is constructed. By examples and contrastive analysis,
this model is proved to be practical and effective.

Abstract—In a trustworthy network with the mechanism of Source Address Validation
Architecture (SAVA), each packet received and forwarded has been ensured to hold an
authenticated source IP address, which can prevent the attackers to forge the originating IP address
to evade responsibility for their malicious packets. However, it is impossible to deploy SAVA all
over the Internet in one night. In this paper, we investigate the SAVA mechanism from the point of
routing for a trustworthy network with a partial deployment of SAVA nodes. We propose a new
routing algorithm, called Minimum Hop to First SAVA node (MHFS). Extensive simulations show
that MHFS can not only guarantee that each route for packets includes at least one SAVA node,
but also achieve a better successful probability for routing packets and a improvement in resource
usage.

Abstract—The possibility of regenerative braking is one inherent advantage of hybrid electric
vehicle. The motor and the hydraulic braking system are braking together while the hybrid electric
vehicle is braking. But, the difference of the braking force dynamic response between the motor
and the hydraulic braking system will lead the inadequate or excessive braking and will effect the
braking felling of the driver. In this paper, we analyze the braking dynamic characteristics of the
motor and the hydraulic braking system. Then, we analyze the hybrid electric vehicle working
patterns of the braking process and design the hierarchical structure of the braking force control
system. After that, we propose the braking force coordinated control strategy based on using the
hydraulic braking force to compensate the motor braking force during the braking process of the
hybrid electric vehicle. This paper used the integrated feed-forward and feedback control to design
the braking force coordinated control strategy. This integrated control can maintain the stability of
the control system while reduce the system error and increase the dynamic performance of the
system. The simulation results show that braking force dynamic coordinated control is effective
and the total braking force can meet the desired braking force during the braking of the hybrid
electric vehicle.

Abstract—For the arrangement of Controls in human-machine interface based on the multiple
operating conditions, the following factors should be considered: the design principles such as the
importance of Controls, operating frequency, operating sequence and relativity between the
Controls, and the total motion distance of the operator’s hand. The arrangement in manual mode

importance, operating frequency, operating sequence and relativity was take as the variables, the
minimum total motion distance of the operator’s hand in the multiple operating conditions as
objective function, and a mathematical model for optimizing the arrangement of the Controls was
established based on Ant colony algorithm. Finally, the process of optimization was introduced,
and the feasibility of the optimization method was proved through a case.

Abstract—A fault-tolerant integrated navigation method for land vehicle is researched in this
paper, which is based on inertial measurement unit (IMU), global positioning system (GPS) and
dead reckoning system (DRS). Firstly, position and velocity outputs of IMU and GPS are taken to
construct measurements of IMU/GPS integrated navigation, and IMU/GPS Kalman filtering
algorithm is deduced and designed. At the same time, position outputs of IMU and DRS are taken
to construct measurements of IMU/DRS integrated navigation, and its Kalman filtering algorithm
is also designed. Then IMU/GPS/DRS federated filter frame is designed, and the global optimal
fusion algorithm of the master filter is researched. Thus estimations of system states from
IMU/GPS and IMU/DRS local filters are sent to the master filter independently. Consequently
global optimal estimations of system states are given in the master filter. Lastly, based on the
federated filter frame, the fault detection and isolation algorithm for IMU/GPS/DRS integrated
navigation system is designed. Simulation results show that, position accuracy of this integrated
navigation method reaches ±4.8m, and velocity accuracy reaches ±0.09m/s. And simulation results
also show that, this integrated navigation method has strong fault-tolerance, and it can keep high
accuracy when GPS or DRS is out of order.

Abstract—The image segmentation based on Markov Random Field (MRF) tries to find the
maximum a posterior (MAP) global optimal solution, which describes image data relations by
local correlations. Comparing with the Simulated Annealing (SA) that is used in the canonical
MRF, Genetic Algorithm (GA) has been applied into the optimization computation. Currently the
weights of energy function and conditional probability are adjusted by generations’ number, which
converged so quick that the roles of conditional probability are nearly negligible. On the other
hand, many scholars defined the individuals of GA as a set of pixels with the gray-level value,
which cause the algorithm sensitivities to the noise and the confusions of gray-level information.
This paper presented an improved GA-MRF with dynamic weights. The improved GA-MRF
defined the labels coding in a neighborhood as an individual instead of the gray-level values
coding in a neighborhood. Furthermore the mechanism of dynamic weights is introduced into the
process of optimizing, which balanced the roles between MRF potential energy and conditional
probability. The followed Synthetic Aperture Radar (SAR) images segmentations experiments
proved that the improved GA-MRF with dynamic weight could reach a satisfied result and avoid
trapping into the over-optimizing by MRF models.

Abstract—In this paper, we propose a new joint user scheduling and beamforming scheme based
on coordinated beamforming (CBF), as called orthogonal linear coordinated beamforming
(OLCBF) for multiuser multiple-input multiple-output (MU-MIMO) systems. With the
assumption that a single information stream is transmitted to each user, the base station (BS) may
select a subset of users from a large number of users by utilizing the feedback of the matched
channel matrix. Unlike the conventional user scheduling schemes in which transmit beamforming
is merely considered, the proposed scheme optimizes transmit beamforming and receive
combining jointly. Simulation results show that the proposed OLCBF scheme achieves a higher
sum rate compared to the conventional orthogonal linear beamforming (OLBF) scheme with
maximal ratio combining (MRC) at receivers when the number of receive antennas is more than
one.

Abstract—Network tomography is a newly developing technology for network administrators to
monitor, predict and diagnose their networks, which is applied to infer network internal
parameters with end-to-end measurement under no participant and no help of internal network
elements. Delay is one of important parameter in network internal performances, so the measure
of delay performance is very necessary. The up-to-date algorithms on delay tomography are
mainly Maximum Likelihood Estimate (MLE) and EM-MLE (Expectation Maximum) algorithm,
but it is complex in their computation, especially when the size of network topology is large. So
the method of moment was proposed to infer the delay performance of internal network. In
contrast to other methods, it is simple in the computational complexity using the method of
moment but its accuracy is not high. In this paper, an improvement is made on the method of
moment, which tries to get higher accuracy in delay distribution inference.

Abstract—We propose a new algorithm, called the central difference filter - Kalman filter
(CDF-KF) for conditionally linear Gaussian state space models. The linear state equation is firstly
inserted into the measurement equation, and the CDF is applied to the new measurement and the
nonlinear state equations to estimate the nonlinear states, where after the estimated means of the
nonlinear states are substituted into the linear state equation and the original measurement
equation to estimate the linear states using the Kalman filter (KF). Moreover, in order to improve
the accuracy of the estimation, the estimated covariances of the nonlinear states are fed back to
modify the estimations of the linear states. The simulation results of the proposed CDF-KF
applying to target tracking show that it only consumes about 5% the computing time required by
the Rao-Blackwellized particle filter (RBPF), while the consistent filtering performance is kept.

Abstract—Rough set theory has been considered as a useful tool to deal with inexact, uncertain, or
vague knowledge. In real-world, most of information systems are based on dominance relations,
called ordered information systems. Although some uncertainty measures to evaluate the
uncertainty of rough sets have been investigated in ordered information systems, the existing
measures are not able to characterize well the imprecision of a rough set. So, it is necessary to find
a new method to measure the roughness of rough sets in ordered information systems. In this
paper, we give a well-justified measure, and some important properties are investigated. By an
example, it is shown that our new method does not only overcome the limitations of the existing
measures but also consist with human cognition in ordered information systems.

Abstract—Multi-target multi-Bernoulli (MeMBer) filter is a new attractive approach to tracking
an unknown and time-varying number of targets. In this paper, we present a new implementation
of the MeMBer recursion—the Gaussian particle MeMBer (GP-MeMBer) filter—for nonlinear
models. The probability density in the multi-Bernoulli is approximated by a weighted sum of
Gaussians, as in the existed Gaussian mixture (GM-MeMBer) filter, but the target dynamics or
observation can be nonlinear. Monte Carlo integration is applied for approximating the prediction
and posterior densities in the multi-Bernoulli and the multi-Bernoulli existence probability. The
simulation results verify the effectiveness of the proposed GP-MeMBer filter.

Abstract—Since the implementation of the new mechanism of Renminbi exchange rate from 2005,
the CNY/USD exchange rate fluctuation range has become more greater than before. Therefore, it
is very important to control CNY/USD exchange rate risk via prediction. This paper is motivated
by evidence that different prediction models can complement each other in approximating data
sets, and presents a hybrid prediction model of support vector machines (SVMs) and discrete
wavelet transform (DWT) to solve the exchange rate prediction problems. The presented model
greatly improves the prediction performance of the individual SVMs models in prediction
exchange rate. In the experiment, the performance of the hybrid prediction model is evaluated
using the CNY/USD exchange rate market data. Experimental results indicate that the hybrid
prediction model outperforms the individual SVMs models in terms of root mean square error
(RMSE) metric. This hybrid prediction model yields better prediction result than the individual
SVMs models.

Abstract—We firstly constructed a new dynamic state space model with little exact knowledge of
the original state dynamics by using the polynomial predictive filter and state dimension extension.
Then a particle filter was used to estimate the extended state, where the sum of the extended
particle weights was applied to test whether the filter is convergent or not. Finally the estimate of
the original state was obtained by wiping off the components corresponding to the backward time
steps. Simulation results demonstrate that, for unknown state dynamics, where the existed particle
filter (PF) diverges, the proposed polynomial predictive particle filter (PPPF) still works well.

Abstract—Arable land has been decreasing due to rapid population growth and economic
development as well as urban expansion. To obtain a better understanding of controlling land use
and to design mechanisms to ensure sustainable land management, an accurate prediction of arable
land is a key issue fundamentally. In this study, artificial neural network (ANN) model is applied
to estimate the arable land change for Chongqing Municipality in China. The prediction is
implemented using a feed-forward neural network, trained by back-propagation algorithm. In
order to investigate the socioeconomic influences on arable land reduction, the ANN model is
trained based on population, gross domestic production and fixed assets investment. Further, the
prediction results from ANN model and linear regression model are compared to test the
performance of model validation. Consequently, artificial neural network shows the ability to
catch non-linear relationships between arable land change and socioeconomic factors and to
predict arable land change with a high degree of accuracy. In conclusion, the ANN model is
applicable of predicting arable land change and some suggestions would be provide for
researchers and decision makers.

Abstract—As an outstanding GIS system, the Google Map provides the public satellite maps all
over the world. The Google Maps API for Flash shows a new way to add interactive Google Maps
application to your website, using Adobe's Flex framework to display dynamic map content. This
API exists as a fully independent alternative to the existing JavaScript Maps API, and provides
many of the features of that API while also adding the ability to mix Flash content with Google
Maps [1]. Google map is widely used as a platform for a number of applications. Nowadays the
travel information shared on the Internet become more and more heated, the application based on
Google map for flash is seldom designed and used. In this paper we proposed the Travel
Information Sharing with Instant Messaging System (TISIMS) based on Google map for flash.
The architecture of TISIMS is described and the implementation is also explained in this study. At
the same time, we introduce a tested prototype as the application of our system. In this system, we
provide users automatic matching the places of interest by users. In that case users can not only
share their travel information to their friends but also acquire the information from them in a
simple and convenient way. Furthermore, the users can discuss and operate a place where they are
interested in with the Instant Messaging System (IMS). The more friends you make, the more
travel information you can acquire. This is what we advocate.

Abstract—The initial sensitivity of chaotic map makes its application more and more widely. The
image encryption algorithm based on chaotic theory is a hot researching field recently. Confusion
and diffusion are necessary methods to realize the image encryption. However, using the initial
sensitivity and randomness of chaotic map can realize the purpose of confusion and diffusion.
S-DES system can encrypt the input binary flow of image, but the fixed system structure and few
keys will still bring some risks. However, the sensitivity of initial value that Lu chaotic map can
be well applied to the system of S-DES, which makes S-DES have larger random and key
quantities. A dual image encryption algorithm based on S-DES and Lu map is proposed.
Compared to traditional methods, it has some merits such as easy to understand, rapid encryption
speed, large keys and sensitivity to initial value.

Abstract—In this paper, an analysis of the principle of the shaking table is carried out and a digital
servo-valve controller for three-axis six-DOF shaking table based on TMS320F2812 is designed.
The result was compared with the analogue controller. AD598 is selected as the
modulator-demodulator to condition the displacement signal of the servo-valve main
spool.AD7665 is adopted to acquire the conditioned signal. DAC7744 is used as the generator of
the driving signal for the servo-valve. The user command signal transfers to the digital controller
through CAN bus from the upper computer. Based on mathematical model of the servo-valve, PID
control law is designed to adjust the control system and a speed feedback signal method applied to
expand the bandwidth of the control system. Through the discrete transfer function of the control
system, software is programmed to test the digital controller. Test results show that the digital
controller is easy to implement and has strong anti-jamming capacity. Additionally, it can
overcome bad consistency of hydraulic cylinder when the shaking table vibrates at high frequency.

mechanic, metallurgy, corrosion properties to the material. We call these areas grain boundary.
People put great emphasis on them and have tried many methods to research them. The grain
boundary has high energy and the energy value is changed with the orientation. Finding the law
between them can deepen the material research. The universal grey set is a set of universal
uncertain information which includes all uncertain information (random, fuzzy, uncertain and grey
etc). Now many scholars have put it into different fields. In the paper the authors firstly put the
universal grey uncertain systems into the grain boundary and establish the relationship of energy
and orientation. The fitting data and predictive data are good. The model is fit for equal and
unequal interval and is deserved to be used into other engineering problem.

Abstract—In the material research we often investigate the mass transport phenomenon. As is
known the mass in metals are transferred by diffusion movement. Most of the physical and
chemical process is related with the diffusion phenomenon. It is the most important subject for the
material science which we call it diffusion theory. Now we usually adopt the experimental method
to research the diffusion in the material. But the diffusion velocity of atom in the metal is very
slow and it takes us much time to observe it. What’ more the movement usually can not observe
directly and we should take many methods to help the researcher to observe it. The grey theory is
an effective method to investigate the poor information and can be used to find the data law on the
basis of a few known data. It has been extended into many fields. In the paper the authors firstly
introduce the grey theory into the material research. Using the step-by-step optimum model GM
(1,1) the authors investigate the law in the diffusion phenomenon. Two examples show the fitting
data and predictive result are good. It is a new way for the material scholars to do the research and
is deserved to extend to other fields. The model is fit for equal and unequal interval which means
it can be easily used in many conditions.

complex nonlinear system. Firstly, fuzzy partition is employed to on-line clustering for the
input-output data; and then, the least-squares (LS) algorithm is employed to construct the local
model for each clustering, and the parameter of each local model is updated by the new data. The
proposed algorithm takes advantage of the TSK model, combines the fuzzy partition and
multiple-model modeling, and updates on-line the number of the local model and the parameter of
each by the input-output data, so as to realize the on-line modeling for the complex nonlinear

Abstract—Singular Value Decomposition（SVD）Filtering is one seismic data processing technique
which uses the lateral coherence difference of the seismic wave to achieve wavefield separation
and denoising. As the differences of propagation characteristics, apparent velocity and coherence
in seismic signals, transformation of the valid signals may be transformed into those with better
coherence by some mathematic transformations. In this paper, based on apparent velocities,
throughing the processing method of two times Normal Moveout(NMO), we make the P-P wave
and the P-S wave moveout respectively that enable them to achieve the best coherence on the
deflection. The goal is that transforms the desired signal to one kind better processing territory in
the horizontal upward coherence, then distinguishes two times SVD respectively and reconstruct
signal with extracting the singular value of target signals. we might accomplish P-P wave and P-S
wave separation as well as noise attenuation afterwards.

Abstract— The problem of semi-supervised dimensionality reduction with kernels called KS2DR
is considered for semi- supervised learning. In this setting, domain knowledge in the form of pair
constraints is adopted to specify whether pairs of instances belong to the same class or not.
KS2DR can project the samples data onto a set of ‘useful’ features and preserve the structure of
unlabeled samples data as well as both similar and dissimilar constraints defined in the feature
space, under which the samples with different class labels are easier to be effectively partitioned
from each other. We demonstrate the practical usefulness and high scalability of KS2DR
algorithms in data visualization and classification tasks through extensive simulation studies.
Experimental results show the proposed methods can almost always achieve the highest accuracy
when the dimension is reduced. And KS2DR methods outperform some established
dimensionality reduction methods no matter how many numbers of constraints, dimensions are
used.

Abstract—An algorithm of target tracking based on adaptive waveform design was proposed with
the help of Doppler estimation theory. According to the analysis of the ambiguity function for liner
frequency modulation signal, a model between ambiguity function of the signal and Cramer-Rao
bound of time and frequency delay was built. This paper realized the target tracking by adjusting
the frequency width and pulse width using Kalman filtering method. With the same signal energy
and noise environment, the simulation results show that the proposed adaptive tracking algorithm
has a better tracking precision than the method which makes use of the constant parameter.

Abstract—Most parts of rotating machine rotate cyclically when the machine fails for some reason,
and the vibration signal of rotating machine often has the cyclostation character. Aiming at this
feature, Degree of Cyclostation(DCS) was presented to analyze the fault trend of rotating machine
in this paper. DCS was constructed by the comparison between third-order non-stationary cyclic
moments and stationary cyclic moments. It evaluated the cyclic frequency with the binary decision
method and it could reflect the non-stationary character of vibration signal and suppress the noise
and interference of the signal. In the experiments of analyzing the fault trend of rotating machine,
DCS could get better trend result than the traditional vibration amplitude and vibration intensity.

Abstract—For multilayer sandstone reservoir , high permeability water passage would be formed
between oil well and water well at the later stage of water drive. This caused the injected water
circulation with no or low efficiency and thus decreased the production of oil wells. In order to
improve the effect of water drive, measures of profile control and/or water shutoff must be taken.
The key problem is to recognize the wells and layers having ineffective or low-efficiency water
passage. In this paper, the identifying indexes have been determined and corresponding
mathematical model has been constructed with fuzzy theory.

Abstract—An optimal planned route is a foundation of safe and economical navigation. This paper
proposes a method for the shortest distance routing in a chart based on testing a spatial relation of
a linear route segment and an obstacle area. Firstly, safety contour traces are traced and obstacle
areas are acquired automatically. Then possible optimum paths circumambulating an obstacle are
searched automatically by comparing the spatial relation of the linear route segment and the
nearest obstacle area. Finally a route binary tree is constructed and the shortest route is obtained.
Experimental results demonstrate that the proposed method has more advantageous over
traditional methods in efficiency, accuracy and reliability.

analysis focus on time-frequency (or time scale) domain, which has also made a series of results.
This paper presents a reversible transform method based on a bit of time series from another point.
Using this method, we analyze non-stationary broadband noise signal according to the different
characteristics between noise and speech signals (such as random degree). Experiment results
show that this method can reverse random sequence of disorder time-domain to generally orderly
time series. The distinction between broadband noise characteristics and voice characteristics is
reversely clear, the method principle is simple, and the algorithm complexity is small which can
be real-time processed.

Abstract: According to the magnitudes of the measuring errors, the measuring errors distribution is
determined by using the distribution collocation test method or figure method, but it is difficult to
obtain the specific distribution. According to the foundational properties of the random errors, this
paper deduces a more general error distribution---the unsymmetrical P-norm distribution, and then
discussing the maximum likelihood adjustment of the p-norm distribution in detail. The
distributions of degenerate、Laplace、normal and rectangular are the specific cases of the
unsymmetrical P-norm distribution respectively. The maximum likelihood adjustment method of
the unsymmetrical P-norm distribution is proposed, and the foundational equations of the
adjustment are given. For each concrete measuring data, we can select a suitable value for p to
make the theoretical model of the error distribution which is used in the data processing be more
closer to the true errors distribution than the normal distribution.

Abstract—The dK-series analysis is an efficient technique to analyze properties of the Internet
topology. Increasing values of d capture progressively more properties of the original topology at
the cost of more complex states. In this paper, we present a new systematic analysis and
generation technique based on the adjacency graph distribution, called dM-series analysis
technique. The dM-series has less states and easier generation algorithm compared with dK-series,
so it is more practical when analyzing large scale networks like the Internet AS-level topology.
Experimental results show that the generated dM graphs converge to the original graph faster than
the generated dK graphs when d increases.

Abstract — Wind speed forecasting is very important to the utilization of wind energy in wind
farm. In order to improve the forecast precision, a forecasting method based on empir- ical mode
decomposition (EMD) and wavelet decomposition combine with least square support vector
machine (LSSVM) is proposed in this paper. The wind speed time series was decomposed into
several intrinsic mode functions (IMF) and the trend term. In order to reduce the nature of
non-station- ary, the high frequency band was decomposed and reconst- ructed by wavelet
transform (WT). The different LSSVM models to forecast each IMF and trend term were built up.
These forecasting results of each IMF and trend term were combined to obtain the final
forecasting results. The simul- ation experiment shows the MAPE is 4.53% about wind speed
forecasting and the prediction accuracy is improved considerably.

Abstract—Random sets theory offers a uniform framework for the multi-source data fusion, and
all problems of the data fusion could be describe, analyzed and solved in this framework. The
multi-sensor multi-target tracking problem could be natural represented in the framework. It is of
engineering importance to tracking low altitude moving targets with acoustic methods due to the
blindness of the traditional radar detecting. In this paper, an algorithm for tracking the low altitude
or ground moving targets is put forward based on the Probability Hypothesis Density (PHD) Filter.
The PHD Filter based on Finite Set Statistics doesn’t need consider data association for
multi-target tracking, which propagates the PHD or first moment instead of the full multi-target
posterior, and it could estimating the unknown and time-varying number of targets and their states
under clutter environment. In the practical, we use the Sequential Monte Carlo (SMC) method to
approximate the PHD. The paper presents a novel and fundamentally well-grounded framework
for tracking multiple acoustic targets using PHD Filter and passive acoustic localization technique.
Simulations are also presented to demonstrate the performance in tracking a randomly varying
number of targets in a clutter environment.

Abstract—In a visual surveillance system, robust tracking of moving objects which are partially or
even fully occluded is very difficult. In this paper, we present a method of tracking objects through
occlusions using a combination of Kalman filter and color histogram. By changing covariance of
process noise and measurement noise in Kalman filter, this method can maintain the tracking of
moving objects before, during, and after occlusion. Experiments which described on several test
sequences of the open PETS2000 and PETS2001 datasets have demonstrated the effectiveness and
robustness of this method.

Abstract—This paper introduces a new wavelet packet image compression algorithm called
WP-SPECK which is based on the set partitioned embedded block coder (SPECK). The zerotree
quantization coding which is successful for dyadic wavelet decomposition is not best for WP,
because the parent–child relationships of tree structures are difficult to define and the probability
of zerotrees are greatly reduced in the WP. To avoid the shortcomings of zerotree quantization, the
WP-SPECK algorithm using block quantization shows lower complexity and more efficient
performance in wavelet packet image coding. Experimental results demonstrate that the
WP-SPECK significantly outperforms the base-line SPECK for PSNR in images of rich texture,
and provides better visual quality in texture regions of images.

Abstract—Exchange rate time series is often characterized as chaotic in nature. The prediction
using conventional statistical techniques and neural network with back propagation algorithm,
which is most widely applied, do not give reliable prediction results. Exchange-rate time series is
also a dynamic non-linear system, whose characteristics cannot be reflected by the static neutral
network. The Nonlinear Autoregressive with eXogenous input (NARX) includes the feedback of
the network output, therefore can reflect the dynamic property of the system. This paper proved
the chaotic property of the exchange-rate time series, calculated the embedding dimension and
time delay of the series, and established the exchange-rate forecast model using the NARX
network. The result shows that the NARX network has better short-term forecast effect,
comparing to the BP network and the SVM model.

Abstract—A construction project is of dual characteristics which are product nature and process
nature. In the study of environmental impact from a construction project, the traditional
component approach can only measure the environmental impact of process nature without the
one of product nature. A method of ecological footprint for construction project (EFCP) is put
forward, including concepts, composition, calculation approach, eco-efficiency and
eco-consumption intensity, according to the basic principle of the conventional component
approach. This new method has improved the traditional component approach, which takes into
account the embodied ecological footprint of buildings as a measure for the product nature and
introduces the duration modulus α. The improved component approach is more comprehensive
and accurate compared with the traditional one. The case study demonstrates how the improved
component approach can be used to fully measure the environmental impact of a construction
project.

Abstract—Support vector machine (SVM) is discussed to use for recognizing cucumber leaf
diseases in this paper. Considering that it is a small number of samples, a new experimental
program has been proposed which takes each spot of leaves as a sample instead of taking each leaf
as a sample. In the experiments Radial Basis Function (RBF), polynomial and Sigmoid kernel
function were also used to carry out comparative tests. The results showed that, the SVM method
based on RBF kernel function and taking each spot as a sample made the best performance for
classification of cucumber leaf diseases.

Abstract—This paper proposes a dynamic Probabilistic Priority Adaptive Time-Threshold-based
bandwidth allocation Scheme for Multimedia services (PPATTSM) in cellular networks. Because
future data service will occupy a large portion of all services in next generation mobile networks
and forced termination of an ongoing call is clearly less desirable than blocking of a new call
attempt, there is much significance in improving non-prioritized handoff data call dropping
probability of Adaptive Time-Threshold-based bandwidth allocation Scheme for Multimedia
services (ATTSM) further. The proposed scheme modifies priority definition and bandwidth
allocation of original ATTSM and then, designs a dynamic probabilistic priority policy for QoS
guarantee of voice service. Simulation results show that the proposed scheme enormously
improves performance of non-prioritized handoff data dropping probability at the cost of slightly
increasing new voice call blocking probability that may tolerate uncritical while keeping high total
bandwidth utilization compared with ATTSM.

Abstract—The order parameter is the key factor of synergetic pattern recognition. However, the
conventional methods of reconstruction of order parameters have some shortcomings which limit
the applications in real world. With these reasons, in this paper, a new approach to reconstruction
of order parameters is proposed based on orthogonal polynomial, and thus we can make full use of
the self-learning ability of synergetic neural network to obtain a group of linear transformation
parameters for order parameters. In addition, a weights-direct-determination method is presented,
which could immediately get the reconstruction network weights in the training process. The
experiment results show that this novel algorithm can not only search the reconstruction
parameters effectively, but also improve the recognition ability of system.

Abstract—To improve the fault tolerance of the distributed spanning tree (DST) structure, we
present an improved DST structure through orderly storing the elements in groups. Further, we
give a representative selection rule, and based on which the node arrival and departure algorithms
are proposed to balance the distribution of representatives in the structure. The maximal difference
of the probabilities of any node to be selected as representatives by other nodes in the groups
within the same level is not more than 1/a(a−1). Finally, we discuss the fault tolerance on the
improved DST structure in a random failures model and an adversarial failures model. The results
show that the improved DST structure is high resilient to fault even if the failures are carefully
targeted. At most O(f/logN) nodes are lost when f nodes failed, and it is better than skip graph.

is builded between the image plane and the laser plane. Through looking up the mapping table and
interpolation method, the three-dimensional points cloud of the parts is obtained. This calibration
method is low-cost, simple-operation and robust. And accurate and fast modeling for parts can

Abstract
Our new reconstructing algorithm is able to reconstruct complex fields without any filter. It was
named Simple Self-correlative algebraic reconstruction technique (SSART), which is one of
nonlinear auto-adapted iterative reconstructing techniques. With numerical simulation, SSART
was applied to reconstructing a complex field in order to test its converging capability. For
contrast, three current representative algebraic reconstructing techniques(ARTs) including basic
algebraic reconstruction technique(ART), simultaneous ART(SART) and modified SART(MSART)
were simulated in the same way. The calculated results and reconstructive accuracy were
discussed with mean-square error(MSE) and peak error(PE). Based on the MSE and PE analysis,
the converging capability of each reconstructing technique was discussed. As the result, SSART
could reconstruct the complex model, but others couldn’t. We stopped iterating after the three
hundredth iterating cycle. With twenty-eight projections, the SSART could reconstruct the model
in a decent accuracy grade by the MSE and PE 0.00024357, 0.61%, respectively. The
reconstructed result by ART only showed outline of the model to some extent. The result by SART
diverged away. The result by MSART showed an outline of the model to some extent, too. It was
better than the result by ART. Our algorithm is a superior technique.

Abstract—A design proposal of BLDCM remote closed loop control system is proposed. There is
a central controller and a networked control interface in the system. The central controller
realizing the motor speed control remotely, is composed of TMS320F2812 DSP and Ethernet
controller RTL8019AS. The embedded Ethernet control interface includes C8051F020 MCU and
Ethernet microcontroller CP2200. The dual-closed loop control method is used in the control
system. A simplified Fuzzy Sliding Mode Control (FSMC) strategy is used in the outer speed
control loop to enhance the real-time ability of BLDCM remote control system. The FSMC
strategy is performed by the central controller. PI controller is adopted in the inner loop current
regulator, carried out by Ethernet control interface. The Ethernet control interface drives motor
operation, runs real-time data acquisition of the operation condition, then transmits parameters to
the main controller via Ethernet. It can change brushless dc motor’s operating mode according to
the instructions which the central controller sends out. Simulation results show that FSMC
strategy applied in the speed controller can obviously reduce the effect of the network time-delay,
and improve the system dynamic performance and robustness.

Abstract—the marine environmental data has a strong temporal-spatial characteristic. The ocean is
always changing. In terms of time scale, marine environmental information is characterized by its
climatology-scale variation features (i.e. year, season) and weather-scale variation features (i.e.
day, hour). The multi-time scale and time-varying characteristics of marine environmental data
products bring foreword higher requirements for data storage and visualization. In this paper, we
use temporal-spatial data warehouse in marine environment data products management. The
marine environmental elements in the data warehouse includes: seawater level, temperature,
salinity, sea flow data field, surface wind field, pressure field, storm surge, typhoon, tide and tidal
current. The type of data products includes: reanalysis, live-analysis, forecast and statistical data,
the total data amount is up to TB level. By record valid time, loading time and existing time, the
data warehouse management service can control the data version, and update data warehouse
dynamically. The temporal-spatial process of marine elements and phenomenon are expressed

Abstract— This paper describes policy-based dynamic resource allocation for virtual machines on
Xen-enabled virtualization environment. Though virtualization technology provides better
utilization of server resources, it adds much more management complexities such as monitoring
and reallocating resources constantly for each domain. Resources consumed by domains may
differ subject to the services provided by domains. And dynamic allocation of resources for
domains might be time-consuming task. It becomes more complicated when the number of the
monitored domains or services provided by domains increases significantly. Our work proposes a
policy-based dynamic resource allocation among multiple domains running on Xen hypervisor
with multi-agent framework.

Abstract—Because of the environment and the nature of the signal itself, GPS or wireless mobile
positioning technology always has any unavoidable defect. But higher coverage percentage,
reliability or precision than single positioning can be gained if integrating at least two positioning
technologies’ advantages and avoiding their deficiencies. So the developmental trend of mobile
positioning technology is hybrid positioning and lots of research has been made. Data fusion is
one of the main methods in hybrid positioning field. This paper gives an effective high-precision
hybrid positioning model with GPS and wireless mobile positioning based on least squares
method and Kalman filtering. Single GPS positioning based on carrier phase is also one of the
highest precision methods, but current difficulty is the fast integer ambiguity resolution. This
paper gives an algorithm based Z transformation to speed up the ambiguity resolution. By test and
verification, this algorithm has a higher positioning accuracy than commonly pseudo-range
differential positioning.

Abstract—A soft sensor was developed to estimate the concentrate grade and recovery rate of a
flotation circuit. The algorithm uses kernel principal component analysis (KPCA) and composite
kernel support vector regression (CK-SVR) to perform the estimation. Firstly, the flotation prior
knowledge and KPCA are employed to reduce the dimension of input vector of CK-SVR. Then,
considering that the characteristics of kernels have great impacts on learning and predictive results
of SVR, a composite kernel SVR modeling method based on polynomial kernel and RBF kernel is
adopted which hyperparameters are adaptively evolved by the particle swarm optimization (PSO)
algorithm. Simulations using real operating data show that the soft sensor provides the necessary
accuracy for a flotation circuit.

Abstract—The evaluation of network security is a hot issue in present research of network security.
After acquiring each host’s confidentiality, integrity and availability evaluation index by attacking
the network, we can directly evaluate the network security. But, for the network with Read-Write
management privilege setting to the root directory, it is necessary to execute the state transition of
the security attribute value by reason of the existence of root directory Read-Write relationship.
Firstly, the Read-Write transition model and correlative concepts are presented for the root
directory with Read-Write privilege setting; then the model transition function is formalized by the
state transition arithmetic operator ⊙. Based on the transition model, we have designed the
network security state transition machine and the network security evaluation model. Finally, the
method’s feasibility and validity are verified by practical example analysis.

show that compared with other multi-path routing algorithms, this one can yield a better effect in
aspects of prolonging network survival time, reducing average network delay and enhancing the

often unable to detect faces with partial occlusion, rotation and strong shadows. To address this
problem, we propose an efficient technique. First, we filter the face-like regions from the input
image using skin-color model. And then component classifiers are used to detect the faces’
components from these potential regions. At last, according to geometrical relation between
components, we locate faces. The experimental results illustrate that this method has superior
efficiency on both of occluded face and non-occluded face.

Abstract—Feature points are an important local feature of an image. Due to the poor performance
in noise endurance of traditional gray weighted centroid algorithm, an improved algorithm is
proposed. By dividing the object region into inner pixel region and edge pixel region, all inner
gray pixels are equalized to restrain the noise. At the same time, all feature points are marked by
connectivity to improve the velocity of extraction. Finally, simulation experimental results prove
that the improved algorithm can extract the feature points effectively with a better noise immunity
performance.

Abstract— This paper proposes a relative shape context and relaxation labeling (RSC-RL) based
approach for point pattern matching (PPM). First of all, a new point set based invariant feature,
Relative Shape Context (RSC), is proposed. Using the test statistic of relative shape context
descriptor’s matching scores as the foundation of support function, the point pattern matching
probability matrix can be iteratively updated by relaxation labeling (RL). In the end, the
one-to-one matching can be achieved by dual-normalization of rows and columns in the finally
obtained matching probability matrix. Experiments on both synthetic point sets and real world
data show that the performance of the proposed technique is favorable under rigid geometric
distortion, noises and outliers.

Abstract—Aerodynamic parameter estimation provides an effective way for aerospace system
modelling using measured data from flight test, especially for the purpose of developing elaborate
simulation environments and control systems design of Unmanned Aerial Vehicle (UAV) with
short design cycles and reduced cost. However, parameter identification of airplane dynamics is
complicated because of its nonlinear identification models and the combination of noisy and
biased sensor measurements. The combined difficulties mentioned above make the problem of
state and parameter estimation a nonlinear filtering problem. Extended Kalman Filter (EKF) is an
excellent tool for this matter with the property of recursive parameter identification and excellent
filtering. The standard EKF algorithm is based on a first order approximation of system dynamics.
More refined linearization techniques such as iterated EKF can be used to reduce the linearization
error in the EKF for highly nonlinear systems, which leads to a theoretically better result. In this
paper we concentrate on the application and comparison of EKF and iterated EKF for
aerodynamic parameter estimation of a fixed wing UAV. The result shows that the two methods
have been able to provide accurate estimations.

Abstract—In the research of locating sudden acoustic emission source the transducers are
generally arranged in special geometries in order to derive the equations which give acoustic
emission source location, and to make the calculations simple. In this paper a new method for
locating plane acoustic emission source is proposed by setting the transducers in a straight line.
This method makes the arrangement of transducers simple, the acoustic emission source location
formulas concise, and the calculations easy. This method can also be applied to the problems of
other source location, especially suitable for the plane source location problems in which the
transducers cannot be arranged on a plane for some reasons.

Abstract—When through-the-wall ultra-wideband (UWB) synthetic aperture radar (SAR) is
applied to imaging, the interference of multipath spreading between targets will introduce ghosts
into the SAR image. This paper proposes a novel technique for through-the-wall UWB SAR
imaging with the capability to suppress multipath ghosts. A multipath scattering model is first
developed for through-the-wall UWB SAR. By analyzing the model, we obtain an important
feature of multipath ghosts in through-the-wall UWB SAR images: aspect dependence. Based on
the ghost’s aspect dependence, we develop a hidden Markov model (HMM)-based method for
suppression the ghosts in the SAR images. Simulations show that the proposed method can
improve the peak value ratio of real targets and ghosts by about 15 dB.

was structured according to the evaluating indicators which include operation frequency and order
and relationships between individuals. The optimization objective was evaluated by the hand
moving distance. This method could be adopted to optimize the layout of components on
human-machine interface in order to ensure safety and efficiency of the system. The troubles of
subjective feelings and randomness are avoided. An example of 13 components is implemented to

Abstract - Many universities and institutes experience difficulty in training people to work with
expensive equipments. A common problem faced by educational institutions concerns the limited
availability of expensive robotics equipments, with which students in the didactic program can
work, in order to acquire valuable "hands on" experience. Therefore, the Robot Simulation
Software (RSS) nowadays is paramount important.
This paper presents the development of a visual software package where a AL5B Robot arm has
been taken as a case study. It utilizes Matlab/Simulink and AutoCAD as the tools for testing
motional characteristics of the AL5B Robot arm. A robot model will be developed; the Forward,
Inverse Kinematics, Velocity Kinematics "Jacobian" and Path Planning problems will be
implemented and tested.

Abstract—A linear blind source separation algorithm based on generalized eigen-equation
resolving is presented. Then a nonlinear blind source separation algorithm is proposed by
extending the linear source separation algorithm to the nonlinear domain. The received mixing
signals are first mapped to high-dimensional kernel feature space, and a feature vector basis given
by the fitness function of the kernel feature space is constructed. Next, in the kernel feature space,
the mixing signals are parameterized by the feature vector basis. Finally, the linear blind source
separation algorithm based on signal variability is applied to the parameterized mixing signals.
The proposed algorithm has simple computation and robustness, and is characterized by high
accuracy. Simulation results illustrate well performance on the separation.

and the initialization mixing matrix of the Fast_ICA was made up of such endmember vectors.
This method could solve the ordering randomicity of independent vectors. In this paper, the
Noise-Adjusted Principal Component Analysis (NAPCA) was used to reduce the dimensionality
of the original data to reduce the calculation. The ICA transformation of the reserved principal

Abstract—EDF is a classic dynamic real-time task scheduling algorithm. In an embedded soft
real-time system, the deadline missing ratio is an important metric to evaluate system performance.
When an embedded soft real-time system is overloaded, EDF algorithm is not effective. In
addition, considering the unsteadiness and unpredictability of a practical task running environment
due to the unsteadiness of network communication and the time estimation deviation, it is
necessary to introduce fuzzy concept and theory to the scheduling field of embedded soft
real-time application systems. In this paper, we proposed a fuzzy EDF scheduling model which is
more suitable for embedded soft real-time systems in the uncertain environment. In our model, all
tasks are periodic and a task‘s criticality and deadline distance are described with fuzzy set. In
scheduling algorithm, tasks with shorter fuzzy deadline distance are scheduled first; to those with
same fuzzy deadline distance level, their criticalities are considered first. The simulation test
shows that our fuzzy EDF model have less deadline missing ratios than those of traditional EDF
algorithm and the important tasks have less deadline missing ratios than that of others tasks in an
overloaded uncertain embedded soft real-time system.

Abstract—When searching for robust optimal solutions in evolutionary optimization, a criterion
for robustness estimation is needed. An expectation-based approach and a variance-based
approach are highlighted in this paper. Experiments are conducted on a single-objective test
function adopting three unequal values of dimension size, solved by an chaotic evolutionary
algorithm. In both former low-dimensional cases, graphical results are given to make a visual
comparison between the two robustness measures, which shows that their searching ability is
complementary. Then a dominance mechanism similar to the definition of domination in
multi-objective optimization is suggested, and integrated with chaotic evolutionary algorithm for
selection of a survival between two individuals in single-objective evolutionary optimization. In
the third high-dimensional case, solved by modified chaotic evolutionary algorithm with
variance-based measure approach, good numerical results are reported.

Abstract—One of the most important problems in pipeline processor is control hazard. It occurs
when a processor fetch and execute a conditional branch instruction. The previous methods like
statically and other prediction methods sometimes does not give correct prediction and the
processor forced to put out the next instructions from the pipeline and the control hazard occurs
and sometimes has relatively high hardware costs like using by prior processor unit method [1] [2]
[3] [13]. In this paper a new method is presented by using an auxiliary processing unit to
determine occurrence / non occurrence of a conditional branch instruction. While being this
method simple, its costs is half of the cost of hardware method for detecting conditional branch by
using prior processing units.

disadvantages that the exact algorithms and heuristics algorithms are difficult to solve vehicle
routing problem with multiple constraints. A simulation model of vehicle routing problem is built

approach. A variety of constraints which VRP problem involves can be processed in the simulation.
As a result, the model has truly simulated complicated vehicle distribution process and simulation
results can provide a basis for various optimization algorithms. The experimental results have
validated the feasibility and effectiveness of this new method. As the simulation results can
document the whole distribution process in detail, this method will have some significance to the
practical application of vehicle routing problem.

Abstract—The method of surface geometry of object recovery mentioned in this paper can gain
3D dimensions of objects surface geometry only using a single image on the basis of brightness
change. In this paper, the background knowledge and the methods related to SFS are briefly

system and a computer. The operation mode is the uncomplicated principle of optical lens imaging.
The core idea of this research is using image shading to recover surface geometry of objects. The
shading is the 3D cues left in 2D image. In the coordinates of light source, the surface normal
vectors corresponding to every pixel are calculated. Then these vectors are converted to the
coordinates of image through the coordinate conversion, so surface geometry of objects are gained.
This paper also analyzed the precision of the 3D recovery results.

Abstract—This paper presents a novel and efficient algorithm for preventing the block wrongly
matching in image inpainting. The proposed technique separates the inpainting process into two
different and important steps. First, segment the pre-selected source area, which is called the
source region, from the input image. This step can prevent the block wrongly matching effectively.
Besides, the adjustment rule of adaptive window is utilized to determine the fixed window size,
which could be adjusted according to the image itself, after that search a best-exemplar from
pre-selected region to fill the image. This step can improve the quality of image inpainting. The
experimental results show the high efficiency and quality of the algorithm.

Abstract
In this paper, we exploit the multi-modal face recognition capability by a comparative study on 8
fusion methods in the score level, including Sum, Product, Max, Min, Decision Template (DT),
Dempster-Shafer Rule (DS), Linear Discriminant Analysis (LDA) and Support Vector Machine
(SVM) methods. Our experiments are based on the CASIA 3D Face Database and can be divided
into two modes: verification and classification. Major conclusions are: (1) 2D modality can
achieves similar performance as to 3D modality, and fusion scheme can substantially improve the
recognition performance; (2) Product rule gives the best recognition performance in the simple
fusion methods without training stage; (3) There is no guarantee that the complicated fusion
methods with training stage will achieve better recognition performance than the simple fusion
methods, and it is important to select the most suitable model for fusion according to the tasks.

Abstract
In this paper, we evaluate the gender classification performance based on 3D faces according to
three aspects: image resolution, data fusion and texture descriptor. Our experiments are based on
CASIA 3D Face Database, which has 123 individuals in total including different expressions.
Main conclusions are as follows: (1) Image resolution has little influence on the gender
categorization performance,and there is no guarantee that higher resolution images can obtain
better results. (2) Fusion is useful to improve the categorization performance in each single
modality. (3)Good local texture descriptors can substantially improve the gender categorization
performance, which is even better than that in fusion.
